Me my self have obtained rank 11, rank 9 and rank 7 on my chars from Vanilla. I only play on one of them. I welcome this change, always wanted to wear the set on my warrior.
Though alot of people will buy the boost, to transmog into this gear. People will get tired of it, when everyone wears the same transmog. (Just like they said t2 would be overused, I NEVER see anyone with a t2 transmog, and I play on a full server (Outland EU))
So calm your titties, and welcome this change as we finaly will be able to transmog into this good looking PvP set.
