Hunters, by far the most broken class right now (rdruids being close second). Obviously all their cds are insanely over the top but people still forget they have among the best cc in the game which is all instant, and have great defensive cds with multiple deterrrences and such. Not that the really need it, most games with hunters dont last more than 5 seconds after stampede is popped.
Well I'm almost full honor and have one piece of conquest.
I just ran a full day of Arena to get capped. We ran a team of Holy Pally, Arms Warr, Frost DK (me). The only comps we lost to were any combination of
+ any healer besides a Holy Pally
So those are my picks. As stated by almost everyone before me Heals are redonkulous.
