I'm a big fan of BM Hunters (in trinity teams) this expansion and would personally encourage that instinct to "just go hunters".

Its not just that they're very easy to manage with a GSE macro this expansion: it's also that they're 100% mobile. So many of the mechanics in the dungeons this time around can be neutered by just running around so the swirlies don't hit.

I honestly don't know how I would manage a fight like, say, phase two of Vol'kaal if my DPS couldn't do reasonable damage while moving.
