Now that we have a lot to post we reached a point where we have to plan what items we post on an 12-24-48 hour cycle. The auction house fees for Warlords of Draenor items are extremely high. And the values of the items are really screwed up. A lot of the weapons or armor has an item value of 5-10.000 Gold. But they look plain bad and the chances of selling them is pretty low.
The most simple thing is TradeSkillMaster. This AddOn shows you quite an amount of information in the items tooltip. In my opinion, DBRegionMarketAvg the best source. It tells me the price, an item was posted on all EU realms in the last 14 days. Why not DBMarket? DBMarket only shows you the items value from your server in the last 14 days. This value often gets manipulated. Some people start to post an item with a 500g value for 500.000 Gold on the auction house for several weaks. As a consequence, DBMarket is rising towards 500.000 Gold.  If you use DBMarket with 100% and post your item for 500.000 Gold, nobody will buy it.

The Horde 12-20 (Barrens + Stonetalon Mountains) guide has been rewritten and revamped.  In addition, there has been numerous tweaks to the speedrun route to make things faster and easier to follow.  Also, in case you haven't noticed I am now adding about 40% more info per step and redoing all the images.  Unlike with my previous vanilla guides, I am now giving a brief explanation of where to go and what to do with each step along with any other helpful tips.

A common mistake of new players is to upgrade their gear at every opportunity, paying for a new piece even if it will only add one or two new stat points over an existing item. Likewise, investing in headgear, neckwear, trinkets, and rings at the earliest available levels can also consume valuable cash. While it might seem foolish to leave an available slot empty, you will eventually find something to fill it. Blizzard will see to it via the quest rewards you'll get along the way. In the mean time, the 1 or more you save will serve you well if you invest it wisely. The bottom line is that one can easily level all the way to the maximum relying on just quest/drop greens. The gear you get from regular questing can help you perform well in dungeons, which gets you even better equipment.

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.
The leveling experience for the Burning Crusade and Wrath of the Lich King levels of 60 to 80 has been greatly reduced from 6,689,030 XP to 4,412,600 XP which is a reduction of 34%. This has been a notoriously lengthy leveling section, and this reduction will be very noticeable and appreciated by those players leveling new characters such as those allied races!
I’ve been a WoW player now since Beta and had a few toons that I always max leveled and played on a regular basis. I loved my other toons (have 1 of each class) but the quest/level grinds were beginning to get to me and soon they fell by the wayside of my play time. I started with Dailies and Events guide and once I started seeing how good the app was, I’ve never turned back and picked up all the Alliance mods. I’m now almost fully level 85’s with all my toons. Only 1 level on my hunter and 4 levels on my warrior until I’m done.
This farm is a cool rogue only spot that is more hit or miss rather than a direct gold farm.  Generally we'll be picking pockets for the item Decaherdral Dice.  It's a rare pickpocket drop that ranges anywhere between 28,000 and 35,000g.  The good news is, this spot has soo many mobs that it's literally impossible to run out of mobs to pickpocket, and when you kill them (which you will eventually)  they have fast respawn times.  Within 20 minutes I was able to snag one of these cool toys in the video.  They seem to be rare and have very high selling points.
This farm almost did not make this list. Even though I have had only a little luck with it, it seems to be gathering some popularity in the gold farming community.  Although I feel with the recent changes in 7.3,  this farm is very close to dying out.  Generally what you want to to do is pull every mob you can as you venture to the last boss in the instance.  The only saving grace of this farm (if you can call it that) is that some mobs are GUARANTEED to drop greens.  Guaranteed.  Whether or not they drop profitable greens is a different question, however it's a must-mention quirk you get from running this instance.  It also allows you to get your hands on some rare low level blues.

Skinning is both highly profitable and convenient, in that you will be skinning the monsters that you're already killing as you level. A skinner starts by collecting relatively worthless ruined leather scraps, but soon moves on to light leather, which can be sold for a good profit. An excellent way to farm leather is to skin the kills of other players, especially if you are following along in the wake of a group. However, do wait to start skinning until it's clear that the other player has abandoned the kill. Don't assume that the other player doesn't skin just because they are not a leather-wearer, for example. Note that your chances of getting a better grade of leather increases with your experience; it is possible, though rare, to get light leather from rabbits. Higher grades of leather yield higher profits. A skinner/miner has potent earning power through the auction house, but often runs out of inventory space.

The last tool is the total knowledge of experienced gold makers. Obviously you are already seeking this out as you are here. I have linked to several youtubers throughout the post, so make sure you check out the ones you like. Check out the list below for some other resources you should check out, including my Discord server for spreadsheet support.
The Horde levels 50-60 guide has been rewritten and revamped.  My 1-60 Horde leveling guide is now completely updated for the 1.12 Drums of War patch.  As you can see it is about 15% larger than the 40-50 guide (single largest guide page yet).  There is also a lot of route changes.  I moved the entire Silithus section from level 55 to level 58, which allowed me to include a lot more quests for that zone.  There is also a lot of other improvement to the route, including adding a lot more quests into the guide, mostly from Moonglade, Silithus and Eastern Plaguelands.  This will make the final level 59 grind much shorter.
The guide should advance to the point where you are in the zone's progression. There are a few steps that can-not autocomplete and they should (hopefully) have comments to the effect of -- you need to manually check this step off. -- For some reason you have to click these steps off 2-3 times to work. (the first time will move the tom-tom arrow, the 2nd time unchecks it and the 3rd click advances the guide).
It's hard to step out of the shadow of Legion, which was utterly fantastic in almost every way, to enter an expansion where you get one item per boss in the last expansion because the rules have been changed to force more grinding, where you have to grind reputation in the old expansion that you probably skipped because rep grinds suck JUST to unlock allied races (who aren't fully unique races since they recycle old content such as animations), where questing has SOMEHOW become boring again and where your new abilities are given by items you'll swap out every level, meanwhile being only boring passive effects no one cares about.

Similar problems have risen in the leveling system, which automatically scales to the player’s level and equipment. For the most part, you’ll vaporize enemies more quickly as you gain power, but there are some weird dips. Many players complained they felt less powerful at level 119 than at level 110, a problem I experienced myself. And world PvP remains a strange and whacky world where level and class balance issues make wins and losses feel destined instead of earned.

1. Don't just take anybody with some gold willing to go. Make sure they at least have some heroic gear or better. Bringing someone in greens not only hurts your chances of killing the bosses, but these players often anger those who are in better gear that need one item and then get outbid by some "noob". You are looking again to establish relationships and repeat customers!

Now that you have these addons, it is time to set them up properly to be used as effectively as possible. With the first addon listed, Auctionator, you will get three additional tabs when you open up the auction house: buy, sell, and more. Buy and sell are easy to follow and read, the primary reason why this addon is the top choice and listed as number 1. You can easily set how much to buy or sell, ranging from 1 individual object to stacks of the same good. The most important way to search is by price per individual item. This will avoid both overpaying and underselling, since you can see what one item in a stack is worth compared to what it is worth when being sold on its own. The "more" feature provides an easy-to-follow window of all your auctions up and the details associated with your auction, such as price and time left, in a nice color coded fashion. Without this addon, you will be severely crippled compared to anyone using this efficiently. If you are afraid of addons for security reasons, the rest can be ignored as long as you have Auctionator!
That being said, there are occasions when a little kindness is not unwarranted. A typical example is a new player who just dinged level 20. They are suddenly confronted with a whole set of relatively expensive skills at his or her class trainer, and the cost of mount and riding training, and needs a small amount of money to learn those new skills. Likewise, sometimes one sees a player who, just by the way he or she walks, is clearly a new player. Kindness to non-whiny, well-intentioned, legitimately inquisitive newbies is karmically rewarding, and one should not worry about shelling out an occasional boon to such players. Remember, at that level, a few gold can go a long way. Heck, even a few older bags that you have lying around collecting dust in your vault will often be much appreciated.
Swim Speed Potions (used especially at lvl 37 for Faldir's Cove in Arathi Highlands and lvl 57 in WPL).  Try to get multiple stacks of these.  I also recommend keeping a stack of these always in your bags.  You will frequently pass rivers and lakes and can use these potions to pass them faster through out the guide.  Please note that these potions do not stack with Druid's Aquatic Form and Glyph of Aquatic Form.

To exit a instance quickly. Create a group in the Group Finder when you are finished in the instance, then leave the group. You will then be ported out of the instance after a minute. When you got a dungeon down, you can make and leave the group around one minute before you reach the end of the dungeon and you won’t have to stand around and wait for 1 minute. This will teleport you to the nearest graveyard, on most dungeons this is right outside but on some there is a bit of a run.

Another potion of treasure finding farm that was made extremely popular by the YouTuber Oldbess.  In this spot, you are simply to patrol the entire southen river basin in Twilight Highlands, just around the Verrall Delta area.  The goal of this farm is to kill water elementals for their volatile water, which trends around 50g per drop.  Combine this with the cloth and the treasure chests, and you have a cool  nifty farming spot – thats rarely populated these days.
If your pet's health gets too low or its attacks aren't very effective against a certain combatant, you can always switch out your current pet with another companion on your team. Only pets that are considered active (i.e., those in your three Battle Pet Slots), may be switched in and out during the battle. Once the match is over, you can always change up your active pet team, which is useful if one of your pets is low on health or dead.

The downside is that War Mode will make you vulnerable to other players, which means you might be killed more often. Whether it’s worthwhile will depend on the zones you’re visiting and how active the other faction is on your server cluster. Heavily populated realms usually mean more players on both sides, and more conflict, but on quieter realms, you may rarely run across an enemy.
The biggest gold maker in BfA for inscription is the Darkmoon Decks. In fact they are pretty much the only truly profitable recipe this expansion. Milling is a pain as you generate thousands of useless ultramarine pigments. You can use some of you crimson and ultramarine inks to craft Tome of the Quiet Mind to get rid of them. I have also found that the item level 300/310 off-hands that inscription can craft sell quite well.
Good question. Me personally, when I use a new strat from somebody else, I always read thru the strat, and in the case I really need to level some pet, I then (likely) exclude strats that are mentioning things like “RNG”, “risk”, etc. But: I’m always happy (when using a new strat) when I see some detailed infos, so that I can estimate what is going to happen. But YMMV.
