Difficult to do when you constantly take autos. Easy with DRK thanks to TBN.
DRK has better personal mitigation than WAR. You can supplement any CD with TBN for mitigation that surpasses anything WAR can conjure up. TBN can be used while in dps stance, and it's better than IB.
so no, what is offered by DRK might have some aspects that is shared with the other tanks, but it definitely has its own unique flavor and can exceed where the other two don't.
