Another thing that people forget is that Drk gets more dps being the MT vs being the OT due to blood price and reprisal. Even in pugs if I have a nin with a pld I tell em I'm gonna MT people have this fallacy in their head that pld is the defacto MT when they're not, any tank can be but drk benefits the most out of war and pld. Try having the drk MT and practice your dps more while being in sword oath then grab a ninja to compare that's the best I can tell you.
