Getting refused to EX groups as a DRK

[Krr]

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.

You just described two things Warriors have - great AOE control and high(er) DPS. They do so at no cost to utility and have equivalent or better maintanking abilities.

I think they're really just missing one more strong anti-physical ability. And some utility.

Yeah this is pretty much it. A tiny EHP bump, one more reliable button for anti-physical damage (even if it's just a change that makes Dark Dance not crummy and unreliable) and a reason for DRK to ever be slotted as OT over WAR or PLD will make the job competitive.
