Always check each of the prices of the item, and look over a spread of several days. This is not so important on small items, but anything that you are spending hundreds of gold on you need to check prices carefully. It is also a good idea to check a website such as Allakhazam, Goblin Workshop, Wowhead or WoWuction to see what an item normally sells for.
If you bought Legion and have no desire to go through old content, good news! The new expansion comes with a free boost to level 100 for one character. You can buy these boosts from the in-game store whenever you want, but they normally cost $60, so savor this free one. Use it for a class that you are confident you will enjoy. As a fresh level 100 character, you will be able to immediately begin the quest that takes you the Broken Isles, the new region where Legion takes place.
The last farm on this list, actually I was surprised this farm eluded me for so long.  Generally speaking gnomergan is a huge confusing instance that takes some getting used to but if your a high value transmog farmer this does not scare you.  You can pull the entire instance and get access to a plethora of high value loot such a recipes, world drops, greens and even engineer supplies.  Overall this farm is shadowed by the Diremaul farm and Zulfarrak farm, but is an equal change of scenery with a wild card if you get the hot shot pilots gloves OR the mechbuilders overalls worth 400,000g and 60,000g respectively.  A pretty cool neat farm that noone really mentioned until now.
“It’s a heavy responsibility, and it’s not one that anyone on the team takes lightly,” he says. “Our aim in storytelling is always to evoke emotion. If that goes too far, it can feel exploitative, it can feel like players are caught in a situation they don’t want to be in. We want people to stick around, to play with their friends, and to see the end of the story we’re telling.”
If you are dead set on leveling a production trade skill instead of taking two of the gathering skills, remember that not everything your trainer offers is worth buying. While it might be nice to have a long list of colorful shirts and dresses to produce as a tailor, for instance, the truth is they offer very little in the way of potential revenue. Also keep in mind that, generally, whatever items you craft at lower levels will not likely sell for more money than you could have made by simply selling the raw materials used to make them. For this reason, two gathering skills are highly recommended until you get closer to 80 (70 if you don't have the WotLK expansion or 60 if you don't have the TBC expansion).

Former captain of the 4-man MDI team Sinking Ship, and self-proclaimed #2 Balance Druid, Peyton “Tettles” Tettleton’s appearance on the MDI desk will be one for the ages. Overall, his goal for the broadcast is to help viewers understand what makes the runs successful. “There is a lot of nuance in Mythic Plus and being able to teach the path to victory for each team is important,” he said. You can catch him on his stream or on YouTube where he primarily focuses on PVE content. He also authors the Wowhead Balance Druid Guide. He loves a good-natured meme and ridiculous photos of himself photoshopped.
These keystones will allow teams to make five attempts at each dungeon in the three-dungeon pool. Players will be informed of the dungeons and affixes 48 hours before the Time Trial begins, which will run every week of the Spring Season, alternating each week between East and West. Each week will feature different dungeons and affixes to keep players on their toes - this element of mystery will ensure fresh challenges and more chances for teams to make the top 8 every week!
FYI: If you’re returning to WoW after an extended absence prior to patch 5.0.1, it’s possible that you’ll have more than the maximum pet limit and/or more than 3 of a kind. However, this will be the only time that you’re allowed to surpass these limits. You will have to pare down your collection, eliminating your duplicates, in order to add new pets.
The Heart of Azeroth is an artifact given to the player character from the world soul via Magni Bronzebeard. It is a necklace that can use the power of Azerite, the lifeblood of the embryonic titan Azeroth (See Plot, below). Azerite is similar in function to Legion's artifact power, in that it is gathered normally from playing the game and is used to upgrade an artifact; likewise, the Heart is similar in function to Legion's artifact weapons by having the capacity to be constantly upgraded. Unlike artifact weapons, however, the Heart is shared with all of the player's specializations and can empower all eligible pieces worn simultaneously.
I think you are referring to the Env Bert strat I have linked. Basically I agree. But you might have noticed that I already had added min power to pet #2, in order to exclude some of the substitutes. Though, I didn’t wan’t to do the same with the Blazehaound (pet #1), because I think the strat is doable also with a suboptimal breed. But maybe you are right and I should just exclude any non-P/P breeds.

Picking up herbalism and mining is the best professions to have while leveling. Not only will you earn gold as you level, but you will also get extra XP. At level 20 you will get over 500 XP for picking up a ore or a herb while killing a mob only gives a little over 100 XP. Don’t go out of your way to pick herbs if you are trying to level quickly, but pick the ones that are on your way. Leveling from 110 to 120 can be done pretty quickly just by doing this. There are a few items that will help you if you decide to use professions while leveling:
Unless low quality items have some known quest use or are coveted by other players, you should try to sell it as soon as possible to create bag space. Always (or almost always, see above exceptions) keep things like cloth, leather, herbs, or large stacks of white/gray items over other loot when you have to decide what to keep when your bags get full. It might be worth your while to invest in larger bags (10-20 slot), especially if you know a tailor.
The home page for the guide says that using it is like having a leveling guru giving you constant advice. Having used the guide for a quite some time now I’d say that’s pretty accurate. You’ll always know what to do and where to go next, automatically. Remember all those questions in the in-game trade chat, asking what to do or where to go next (for whatever level?) It won’t be you asking those questions.
PLUNDER THE ISLANDS OF THE GREAT SEA – Explore Azeroth’s uncharted isles in Island Expeditions. Battle in groups of three as you race against cunning rival intruders (or enemy players) to collect the island’s resources and fuel the war effort. Constantly evolving challenges await as you traverse frozen landscapes near Northrend, open the gates of an abandoned Gilnean castle, navigate a war between elementals, and more.
The most rare and expensive poly morph tome drop and for a reason.  The bears that drop it are VASTLY spread out across the zone and getting one can mean hard farminh for a while.  They also take a while to respawn so watch out.  Getting one to drop can mean a staggering 48,000g, and on top of that compared to other pet farms and such, they have a much higher drop chance.  Simply head over to dragonbligh ona mage character (class trial is perfect) and start the killing.  Cross you fingers as there is an 0.4% chance to get one on each kill.  Thats actually pretty high considering..

Why don’t you go for a Guiness World Record? (The answer is that I applied for the World Record as Richest Player in World of Warcraft in November 2015 but they “do not invite proactive applications for records such as the one you are proposing” and suggested I go for “world’s longest Warcraft livestream” instead. Zzzzz no skill needed, no thank you!)
If you are not the leader of a high tier guild, do not worry because you can still make gold off of raids. This is the newly emerging GDKP runs that a respectable raider can put together (See why it is so important to keep a good reputation on your main toon?). Respectable raiders often take a few of their friends they can trust that have a lot of gear and bring random people along through the raid. Whenever a boss is killed, the items are auctioned for whatever base price you establish or more. You then split the money with your friends to keep everyone trying and happy, while you become richer without doing anything out of the ordinary. This seems like a perfect idea that can not fail, but it still has its risks. The tips below will help maximize the potential of the GDKP run.
Most classes in World of Warcraft start at first level, but Death Knights and Demon Hunters are exceptions. They start at level 55 and 98, respectively. This alone can shave a huge chunk of time from your leveling experience. Of course, it only works if you want to play a Death Knight or Demon Hunter, but they’re both solid classics that can dish out damage or tank in a group.
SSC has been known for it's abundance of pet drops, which is why this farming spot exists.  It can only be done once a week by each of your characters, so make sure to hit it if you can.  Generally you'll want to kill all the bosses for a chance at their rare pets.  Everytime I go, I have the luck of getting one, in the video I actially got the Tideskipper to drop, and a video I done on the spot before that, I got the tainted waveling.  So yeah. It's a pretty awesome spot with high rewards and also some world drops.  I was able to snag a will of edward the odd as well, totalling a nasty 35,000g.  The most important part is that you kill the bosses, the pet drops do sell, and they are very easy to get.  Well worth the time invested.
Any item with a grey name is considered vendor trash or poor quality. White items have some use such as tradeskills, spell reagents or reputation raisers, so you may want to check to see if they're worth more than the vendor price. Keep your eyes out for regular quality weapons, as even the worst of these tend to sell for several silver, or several gold at high level. Always check the tooltip for the vendor price before discarding anything. Also, white (or even grey) shoulder armor under level 20 sells regularly on the auction house, mainly because there is nothing better available at that level.
The neutral auction house can become one of your best friends. Other players are constantly checking both factions' auction houses to find an appropriate price for the good they demand. Often times, goods are cheaper on the alliance because they have more people, thus, the supply increases as demand decreases and price goes down. If you are horde, feel free to transfer gold to your alliance toon through the neutral auction house in order to buy them item and bring it back to the horde side where it is more expensive. The 15%, as of patch 3.3.3 (down from 30%) is well worth the extra 50% or more you can easily make on one item alone. Blizzard decreased the neutral cut for a reason to 15%, that reason is to get trade facilitated between the horde and alliance. Make sure you take advantage of this! Tips when trading between factions:

One thing to realize is that once you hit 15 you have a lot more options for speedy leveling. Right now (you seem to be level 9 at the time of this writing) you only have questing and grinding, which are inefficient. Once you get the ability to use the Random Dungeon Finder (often called LFD, Looking for Dungeon) you can queue for dungeons in between questing. Often one dungeon, up until 25 or so, will give you most of a whole level off the XP and quests within.
I recommend not counting on transmog sells for your monthly gametime. Its a great market, but also pretty random. You have to have the right items posted at the right moment if a player needs a certain item. If this is not the case, of course you will not sell anything to him. There are people making millions of golds a month with transmog. But they are very professional at it and it really takes a lot of time.
Note that these general principles do not apply to blue or purple items. If you are a first-time player, there is absolutely no reason to purchase these items. None. Sub-80 rare and epic items are only for the alts or twinks of established players that have money to waste (because that's what it is) by showing off their Staff of Jordan (or whatever). Blues and purples are completely cost-ineffective for first-time characters. Within a few levels, you will find green gear that is roughly comparable, or you'll get better blues from instance runs at the same level. So, do not buy these items, under any circumstances, if you are a first-time character (no matter how cool they look). And even if you're reasonably well-off financially, think twice. This is especially true as your character gets closer to levels 58 and 68. Even the most basic quest-reward gear in Outland will have substantially better stats than anything you can buy off the AH for a level 56 character. The same is true of Northrend gear at level 68 vis-a-vis the stuff you'll get in Outland at level 68. As such, smart players stop making AH gear purchases by about level 54 or so, and then just gut it out until level 58. The same is true at levels 64-68. Within the first several quests in Hellfire and/or Northrend you'll have replaced half of your gear in any case, guaranteed.
A "stat squish" and "item squish" was implemented to lower the numbers used in the game, e.g. a legendary item previously with a level of 1000 reduced to 265. Unique class-specific buffs are added back, i.e. mages' Arcane Brilliance and priests' Mark of Fortitude. Titanforging—a random event that raises the initial item level of an item gained via drops or rewards—is still in the game; however, if the item is one of those affected by the Heart of Azeroth, then that item cannot be titanforged.
2. Once you have an interested buyer, stay firm in your price. This does not mean to never make them feel like they are getting a bargain. You can subtract 5% off the price and not be hurt as long as you still make a profit! Remember this, as that 5% may not be a big deal to you, but the buyer will feel special and might buy the item for the slightly reduced price. I can not emphasize enough that this is not the same as undercutting! Do not drop every good every time or you develop a reputation as a soft seller and people take more liberties in their dealings with you. If you give someone a constant 5% discount, then they begin to want 10% and then 15% until you no longer make a profit. Discounts are used when you feel that the seller may be pulling away and you really want to just profit and move on!
