-New dungeons- About 3/4 are fairly decent, not too long not too short, but none of them are compelling, none make me say to my friends and guildies, "Hey, let's do this instance, I love the theme and encounters." They're dull but tolerable. The other 1/4 of the dungeons just aren't fun and you will groan when you get a mythic Keystone for the Underrot, the snake temple, or Waycrest Manor. Waycrest Manor is actually one of the better dungeons, however, with the new Infested affix, Waycrest Manor suffers from many game-breaking bugs that end in the entire instance being pulled due to doors not properly working as intended.

Okay, speaking of pet farms this one is a really unique farm.  What we're looking for is the carrier cage : black tabby.  This is a very sought after pet for both horde and alliance – which is why its price competitively at 55,000g.  The farm takes place in Hillsbrad Foothills on a peninsula like piece of land just northwest of the yeti caves.  There will be dozens of stormpike engineers surrounding ballistas that only horde characters can kill.  However, that doesn't mean alliance polayers can't do this farm (im alliance myself).  All you need to do is to create a class trial (monk is the best) and send him over to the grinding spot.  Use the black ox statue to attract the mobs, and easily maul them down group by group.  If luck is on your side, you can make out with an awesome black tabby carrier.
Herbalism is also a good source of money. Herbs are required by alchemists and scribes. Unlike ore which is found only in rocky areas, herbs can be found in many places. Be sure to check on the auction house for what herbs are in demand for a high value; often a lower level one is very valuable, so you can farm an area you already know for quick money.
I'm very, very interested in a guide that takes into the following: 1) Dungeon finder; and 2) Heirloom items. I've never helped with a guide before, but would be open to help in collaborating on the project. With the leveling guides I've used (primarily this one) I, too, find that I level at a rate that throws the pace of the guide way off (not its fault at all, I can't say enough good stuff about the guide) to the point that I get frustrated and just queue up for dungeons.

Engineering is a crafting profession that primarily revolves around fun recipes. The gold-making potential from engineering is limited in terms of Legion recipes. The Skullblasters can be obliterated for profit. Engineering has a lot of profitable old world recipes, primarily mounts and various unique effect items and toys. This profession is best relegated to an alt unless you love the lore-aspect or have other sentimental reasons to keep it on your main.
New to Patch 8.1 is a new leveling flask called the Draught of Ten Lands which increases all primary and secondary stats by 20 and experience gained by 10%. This effect lasts for one hour and persists through death, similar to other battle flasks. This item can be purchased using a new Patch 8.1 currency called 7th Legion Service Medal or Honorbound Service Medal which can be earned doing the new incursions and Warfront activities. Simple earn these medals on your main character, purchase the flasks, and send them to your other characters. The cost is 10 of the medals.
It’s a good thing that the previous expansion, Legion, was the best in the game’s history because Battle for Azeroth is coasting on its success. The major class redesigns that happened then remain in effect (though some are a little worse, and some a little better), and the combination of World Quests and Mythic+ dungeons means there’s always something to do, no matter your skill level or how long you can play.
Once you get to about 200g, the theoretical limit of your profit virtually disappears. You now have enough money to start mass buying and reselling those players' goods who undercut everything by an extreme amount. Enchant mats are still a very good focus during this period, especially essences and crystals. You can now afford to buy several maelstrom and abyss crystals and wait until prices fluctuate to resell for a profit. A major strategy you can begin to employ is the multi-character trading and auctioning. If you come across 5 abyss crystals, get onto one character during peak hours and advertise a price 25-50% higher than average. When no one responds to this, quickly switch to another toon and offer the same 5 crystals for 10% lower than before. This will help to raise the median price because other sellers see what they may be able to get for their good. While they are cancelling and reposting, take this time to undercut their new prices, which is now more than you ever could have gotten before when prices were low. If you master this with BoE epics or more rare items, then you can make differences of thousands of gold.

Sylvanas initially planned to simply capture the city, holding its inhabitants hostage. But after the Night Elf leaders were able to escape, rather than cut her losses, Sylvanas ordered the Horde to burn down the entire city, slaughtering hundreds, maybe thousands of innocent civilians. As a noble, honorable faction, many Horde leaders (and indeed, players), were alarmed by Sylvanas' actions, forming the basis of the Horde story arc moving into Battle for Azeroth.
Now that you have the addons and the websites needed for success, you are ready to make auction toons. You will want two auction toons, one on the same faction as your main toon and one on the opposite faction. Do not use your main toon to make the auctions that get you gold! This is one of the greatest mistakes you can make because after a while, people will get annoyed with your prices and selling quantities and begin to blacklist you from groups and some will even boycott your products. Do not risk this happening to you, but rather, create an orc for horde and human for alliance and get them outside the nearest auction houses in Orgrimmar and Stormwind respectively. (As a personal preference, I tend to avoid names with bank, mart, or sell in the name because when negotiating outside of the auction house, you seem less personal). All the addons we downloaded should be enabled for these characters as well. 

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.
The other addons are a great addition to the repertoire of the gold maker. Some add percentages and buying lists, while others provide price and revenue graphs to the reader. Chatter even allows you to repeat those WTS messages without sifting through pointless gossip and chatter. The in-depth workings of them will come later, as for now, more basic setup needs to be covered first.
Another terrible one. I'd have initially thought the bloodlust was kinda useful since you won't have to waste money/effort on drums, it can't actually be used in instances so woo, a free BL in the open world that doesn't even buff your party members... and when both mail classes already have a BL, I mean, really, what's the point? The mount from the initial design could have at least been unique and possibly had a use, but this is very disappointing. The passive buffs outside don't appear to be anything spectacular or interesting either, though I suppose might be useful if you stumble upon them while doing world quests or whatever. I would recommend not crafting this one.
