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.
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.
Void elf - "Many have sought to harness the corruptive magic of the Void. Most who tried have fallen into madness. Determined to use this power for the good of Azeroth, Alleria Windrunner is the first mortal to succeed at defying the shadow's whispers. Coming to the aid of a group of her kin who nearly gave in to the darkness, Alleria has vowed to train these Void Elves to control the shadows within them and pledge their newfound powers to the Alliance."
Isle of Quel'Danas: Special mention. At lvl 70 you can start doing the dailies here. Despite not being able to fly, the quest density is VERY high. I recommend hitting this every reset if you spend more than 24 hours REAL time(not /played)in the 70-80 level range. In fact, if you're doing a monk and only logging in once each day anyway, IQD WILL be your best exp/h for this level range.
Anything that can be answered by reading the recent discussions on the subreddit, has a yes/no response or can be looked up on sites in the community resources should not be posted in a thread of its own. Questions such as 'What is this worth?', 'Did I make a mistake?', 'What do I do with XYZ?' or 'Should I buy/sell this?' will be directed to the Daily Questions sticky.
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.
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.
Zandalari troll (8.1.5) - "The Zandalari are a proud people whose origins date back to the early days of Azeroth's history. Their fierce warriors ride dinosaurs into battle, and they possess one of the most formidable naval fleets in the known world. But enemy attacks on their borders—as well as unrest within the king's council—have threatened the kingdom's foundations. By returning stability to Zandalar, the heroes of the Horde can gain a powerful new ally.."
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.
The World of Warcraft playerbase is cut in half, but not in the usual “Horde versus Alliance” fashion. Instead, Horde players themselves seem at odds with what their faction actually stands for. Cobo and Lo suggest that this mismatch may be hard, if not impossible, to fix. Someone is always going to be disappointed, and with Cobo’s talk of honor being at the center of the Horde, Sylvanas-stans will probably have a disappointing time with the expansion.
For this farm we're taking it all the way back to eastern kingdoms. We're going to be killing the purespring elementals in the purespring cavern for the item essence of water. Essence of water is a semi-rare drop that goes for a shocking 252g per piece. The caveat is that it doesn't drop all too often, but is still worth the trouble. I wasn't getting TOO many of these, but I was still making bank with them. The essences are used to create the old-world illusions, so they do have some inherent value. Simply patrol the area and kill as many elementals as your heart desires. It's a really cool and fun farm that can be done on autopilot. Usually there is noone patrolling the spot.
Heart of Azeroth: Our world is direly wounded. Players will be summoned via Magni Bronzebeard to Azeroth herself. She will gift players with a medallion called the [Heart of Azeroth]. Her life essence seeps from the world in the form of [Azerite]. When players wearing the medallion come in contact with azerite, this sought after resource becomes a source of power for selected pieces of armor, providing players a way to level them up. This feature replaces the artifact system of World of Warcraft: Legion. Currently the plan of development is to limit the upgrade system to 3 pieces of armor. Players will be able to choose the stats they want to better fit their play-style.
In World of Warcraft®: Battle for Azeroth™, the seventh expansion to Blizzard Entertainment’s acclaimed massively multiplayer online role-playing game, the fall of the Burning Legion sets off a series of disastrous incidents that reignites the conflict at the heart of the Warcraft® saga. As a new age of warfare begins, Azeroth’s heroes must set out on a journey to recruit new allies, race to claim the world’s mightiest resources in order to turn the tides of war, and fight on several fronts to determine whether the Horde or Alliance will lead Azeroth into its uncertain future.
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.
