Feral is still good..
Unholy death knights, Spriest, hunter very strong.
Powershot can crit 140-160k easily.
Monk Fists of Fury still can bring solo target down from 50%.
The most common setups are spriest-rogue-x,spriest-mage-x,kfc.
After a couple of games I am still sticking to DoC talent, it is somehow feels stronger. I mean dropping a 163k heal on my friend while he was dying just felt too damn awesome, heh.
