Our team plans on running Arms warrior, Unholy DK, Prot / holy paladin(until it gets nerfed). I keep hearing problems about hunter / frost mage teams with this comp, so heres what I was thinking.
If i went Fury/arms, deep enough to get titans grip and Heroic fury (to remove frost novas), the high burst dps along with hitting multiple targets might help out a lot. Fury warriors also have furious attacks which accounts for the 50% MS. The decreased intercept cooldown is win (15 seconds) and the Rampage buff would benefit the Dk as well. Death Wish isn't half bad either.
I know that Bladestorm won't be available for this spec, but the pressure applied from constant WW's, instant slams, Bloodthirst might be enough to make up for it. Also, I can spec deep enough into arms for deep wounds and 2/3 for increased weapon by 2's by 4%
Just a thought, let me know what your opinions are i'm pretty curious
-Thanks :]
