DRK is overrated this expansion. Its the 'king' of mitigation is a stretch when its not a necessary title in Savage with how few tankbusters and mitigation requirements are in Savage. The reason why its being played right now is Alex mainly due to it having 1 extra CD than all other tanks and the fact that in 1/2 of the fight it can pad its numbers by an insane degree due to double hits.

Its damage though is not worth the playstlye requirement of DRK on single target, its too low for what you need to put into it and should be on the higher side of tanks with GNB, not the worst without party buffs.
