Everything on the WoW-related websites keeps wanting me to (a) see the NPC in Stormspire and do transmutes of primals (removed from the game long ago), or (b) see an alchemy trainer in any faction capital city to get the quest for one of the masteries. I've visited the alchemy trainers in Silvermoon City, Undercity, Orgrimmar, and Thunder Bluff and none of them have the quests.
What lvl do I need to be? What alchemy level do I need? Who REALLY has the quest for alchemy masteries?
