Consumables (Alchemy, Jewelcrafting, Enchanting) – When I have gotten a toon to max level and managed to get all of the end game recipes/ranks, I have done well. However, I never have much luck with the lower level items. It feels to me like if someone is going to buy a gem, enchant, or flask, they want the best one or none at all. Maybe that comes down to the servers I play on, but it does make sense compared to how I play my own toons. I either am going to gear up a toon for endgame or not worry about it at all. Alchemy does have the benefit of transmutes which even the low level ones can make some decent gold. JC does have the MOP mounts and pets if you can get the recipes for them but otherwise these professions feel like max level or bust to me.
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.
All of my gold came from everyone buying stuff at a really marked up price for instance BS 2h mace if it proced epic i was making at least 125k per one and i was making batchs of 10 to 15 it was like 25k for blue and 125k+ for epics at the time. And i was buying the ore for like 16g to 40g a pop so huge profit. Im still trying to figure out what im gunna do now to rebuild it will be a slow process now.
