On offense side what about not adding scourge effect to SE, but simply adding Scourge (Similar style to Goring Blade) to the Syphon Strike combo, the other two tanks get 3 combo enders but DRK gets 2. Possibly removing Bloodspiller and Quietus or at least Quietus off GCD, would allow us to avoid losing resources on its cast. Reduce DP mana cost, and buff potency, and if Blood Price could just give more mana would be great.
