After much research, the only new ability I was able to find that is similar to what the gathering professions got is Mixology, which Alchemists can train at the Master Alchemy Trainer in either Honor Hold or Thrallmar. Our Alex Ziebart and friends tested it out in the beta and determined an approximate 25% bonus when drinking flasks and elixirs. It’s a nice little bonus and I’m happy to have it, I just wish the patch notes had told me it was in the Echoes of Doom patch rather than having to find out from a helpful commenter.
Are the other crafting professions getting abilities in Wrath? The Q&A panel said they were going to make sure all professions were valuable in the endgame. Does that mean more Mixology and Lifeblood-like abilities or other self-only benefits? What abilities do you think the other crafting professions should get?
