Its hardly a killing when compared to other gold making methods, but from a side-hustle that you're investing little time into (ignoring the initial upfront time investment), the amount of gold you'll make will be well worth it, especially if you keep at it. On my main server, which I've been operating in the manner above for around 5 months, I have around 1100 items, and bring in approximately 50k per day from transmogs alone. If you're willing to pump extra hours into consistently farming for transmog, this figure could be bumped up significantly.
Enchants. I honestly wasn't 100% certain which enchants were best, since scaling has screwed up a lot of things. IMO, just pick the enchant for each armor slot that has the highest bonus without level restrictions. The exception is that you'll definitely want Mark of the Hidden Satyr for your neck piece, and probably Elemental Force for your weapon. Both of these proc consistently and strongly across all levels.
“It’s challenging for sure,” said Cobo. “but I think that, ultimately, we have to look at what’s at the core of the faction [...] Everything is about honor when it comes to the Horde, and as the story unfolds and you start to learn about the motivations behind Saurfang, or the motivations behind Sylvanas and why she’s doing what she’s doing, it starts to create a perspective around, ‘Is that the kind of person that I want to follow?’
This is a VERY GOOD potion of treasure finding farm that generally shocked me when I stumbled upon it.  In this video it's one of the more popular farms – just because it's potential to tap into soo many different markets (especially if you are a skinner).  It takes place at the pit of scales near the foot of the uldum river.  It allows you to not only gather tiny treasure chests faster than any other spot, but also awards an obscene amount of leather.  Just step on the eggs and 5 crocolisk will attach to your character.  Kill them all and start skinning them.  There are 6 egg spawns with very short respawn timers surrounding the area.  You will literally never be waiting for respawns.  Again, skinning is a must to take advantage of this mega spot – and even though, I feel only a handful of farms surpass this one, It's truely my favorite.
I am currently working full time on my Vanilla WoW leveling guides.  Soon there will be a 1-60 speed leveling guide for Alliance, along with in-game guide versions available for my members area.  As of right now, there is no members area, but if you would like to show support for my efforts into this project, you can simply donate to me via Patreon if you like (you will get some cool rewards in return).  Or you can donate directly with PayPal if you like.  All donations are highly appreciated and they will only motivate me more to continue making the best vanilla WoW leveling guides on the web.

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.
When buying raw materials from the AH, keep an eye out for bargains. Choose only the cheapest items available to keep costs down. Try scanning the whole section of item listings in the AH to check prices; often the prices for stacks of items in the AH are much cheaper than individual pieces (for example, a single Thorium Bar may be priced at 3 , but a stack of 10 may actually be priced at only 2 per Thorium Bar) — you may spend more to acquire your materials, but you also save more and ensure larger profit in the long run. You can find a lot of terrific bargains this way.
Heart of Azeroth:[5] 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.
At 96 the standard wisdom is to immediately drop what you're doing and proceed to Spires of Arak and do the quests to unlock the Inn, granting a further 20% experience bonus while in that zone. You'll want to do that eventually anyway, but I'm not sure it outweighs the quest experience from Gorgrond. However, if you decided to go to Spires immediately at 96, restrict yourself only to bonus objectives and again leave Treasures until you're 100+. Make certain that when you being the quests to unlock the inn, you speak with the quest NPC to also learn Archaeology, since it's required to collect several of the treasures in Spires.
Once your auctioning operation reaches a certain size a second account becomes an invaluable tool. It will allow you to run auctioning scans, shopping scans and collect mailboxes while playing your main. I strongly suggest buying a second monitor as well. This will help you really unlock the benefit of a second account. For a detailed guide on why and how to set it up check out my post on the subject.
If i start on a new realms, I am farming a lot of transmog from classic and Burning Crusade Dungeons and Raids. In the beginning, i start to post them if they have at least a DBRegionMarketAvg (Average value of an item on all EU realms of the last 14 days) of 500 Gold. All the other items get vendored. The time you hit a stock of 1000 Items, my value treshold raises to around 2.500 Gold. All the items below that value get vendored aswell. Newly farmed items that are above these treshold will be listed. Why? If I start over somewhere, I want to get a certain amount of gold quickly. Cheap items are great for that. Later on, to save time, Quality is better than quantity. As mentioned above, re-posting the items on the auction house takes quite a bit of time. At this point, I can recommend you the TradeSkillMaster AddOn, it makes your auction house work really a hell of a lot easier.
