Based on what Camate posted in another thread, it sounds like vanity slots are confirmed for 2.2, not 2.1 or post 2.1. I am also extremely disappointed in how it sounds like they are implementing this. The way they describe it, is NOT vanity slots like Rift, but transmog instead. Ugh. This is the one feature I've been very much looking forward to, and learning this has greatly decreased my interest in the game.
