Getting refused to EX groups as a DRK

[Faytte]

and a Sentinel that only works on half the attacks in the game.

1) A 10s Vengeance that only works...
2) Probably less than half

That said, DRKS have other things other tanks DONT have--amazing aoe, 2000+ potency off gcd per minute, etc etc. Not saying its rosey, they definitely need some work, but i cant imagine them getting really strong defensives without re-balancing elsewhere.
