Warriors and by far the most fun, to me. You just have so much you can do. Charging, leaping... like a master of the battlefield. Since the shield barrier is an absorb, rather than a heal like SD... i dont have anything stopping me from hitting it if my health is high. Everything flows, from one move to the next.
Dks and Paladins, play like they did in cata. A few abilities are altered, but basically, it's still the same.
