Was going to stick to my Undead Hunter, but lookin' at how untouched/uninteresting our talent choices are as BM/MM (and Surv seems like a straight clusterfuck), I might actually re-roll.
On the PTR, so far the specs I've enjoyed the most are: Frost/UH DKs, Feral/Balance (and their tanking specs), Frost/Fire mage, Fury could still use some tuning but the combat animations are tempting me, Elemental (not a fan of Enhance's Rbiter spamfest), WW/BM monks, and Dest/Demo locks. The rest felt meh. Ret felt good w/ 9 sec. Consecrate and Divine Hammer but since the bump to 12 sec. it feels slow again.
