World of Warcraft: Battle for Azeroth is the seventh expansion for World of Warcraft revealed at BlizzCon 2017 and announced for release on August 14, 2018.[1] The Alliance, led by King Anduin and Genn Greymane, attacked Lordaeron, Warchief Sylvanas' base at Undercity, in response to the Horde burning down Teldrassil. The factions are at war. Between the Alliance-controlled Eastern Kingdoms and the Horde-controlled Kalimdor is the Great Sea. It is in this Sea that a majority of the expansion will take place.
currently sitting at around 1.1-1.2m gp on my toons, a bunch in my mailbox (i like to clear sold auctions at the end the day), and 3 sky golems to sell. Not to mention i've bought myself a token, and given my brother 2 (he agreed to buy bfa for me vs 3 tokens), as well as blowing 250k on mythic boosts. I knwo others have done way better (hell i knew a guy that had made 4m in like 3 days during the DMC boom) but i'm pretty happy with it

All of this is to say that while you make some good points, such as not trying to farm what everyone else is farming, look for other opportunities, it's not always as simple as just going back to old content. I've heard from many others on this subreddit over the years that the examples I show above are neither unique to my server, nor are they new problems. This might be part of why so many people are expressing difficulty in finding their way.
I think that's server dependant. I make a lot of Golems, but the price on my server is high enough that you could buy all the living steel and still make about 20K (almost 200kg on AH). Its just that you proc all the way up the chain. You proc 20% of your trillium, and then 20% of your living steel. SoH and Ghost Iron are such low effort farms, too. 20% of 180 Trillium Bars at 500g is 18k more profit, 20% of 150 Living Steel at 3500g is another 105kg. That's an extra 25k profit per Golem. If they stop selling stockpile them for the next expansion, they always boom with the price of herbs. And a consistent 20% proc rate is the opposite of RNG, its extra free stuff as a benefit to completing an extra quest (not to mention for new alchemists the investment of leveling Vanilla Alchemy). You're looking for some get rich quick scheme, where the real way to build wealth is patience and volume. No market is going to be viable because you want it to be. Only because you make it viable.
