The Escalation patch has introduced several new scenarios with respective heroic modes that provide shiny new loot. It is still too early to predict which of these will demand the highest prices at the auction house or AH, since it can take weeks for players to work through the content and determine the value of the new drops compared to the existing items. Many expect the rarest and most prized drops to start commanding handsome prices starting June, so just keep your eyes peeled for popular WTB requests in general chat and high-selling items at the AH.
I only play 2 characters and normally have all my Mythic 0s done by Wednesday. After that I come home from work do my Emissary WQs and then farm the Dune Scavenger and Leaping Veinseeker mounts. By doing this I have sold 3 BoEs and about 7 mounts totaling around 5 Million gold. So yeah I would say I made a shit ton during BFA. Before BFA I didn't play since Very Early Legion and only had 170k on my Account and spent that to reactivate my game time. So I was pretty well poor AF. I now have a total of 6,223,576g on my Account. If you focus on making gold you will make gold.
That's where i'm at now. I got into it late. I had 40k to start. Sold fish up to about 100k total starting capital. Started making and selling decks when they were going for 80-200k on my server. Morons have repeatedly undercut decks by 30-60k at a time even after the market has been reset (not by me) multiple times. Now the decks are 25-80k... I did manage to make 3.5m gross in the last 2 weeks. Now the individual cards are selling for MUCH less than the decks so I may stop crafting myself and just start buying the individuals... idk where to go from there though. Do you think the decks will hold any value moving forward? I'm kind of hoping for something similar to obliterum in legion to increase the ilvl and keep them relevant.
