Syphon Strike gives you half the amount you need for Dark Arts, so people add 70 potency has opportunity cost. So, a full powered SE combo deals 150+390+70+420 = 1030 potency over 3 GCD...so 343 pot/GCD with 4800 MP spent.

Basic Bloodspiller is 380 on its own...so it's better on average than you double Dark Artsed SE combo.

With Grit, SS gives you one Dark Arts, so 140 opportunity potency, increasing the total potency at 150+390+140+420 = 1100 so 336 pot/GCD...again, BloodSpiller tops at 380 even before considering the impact of Grit.

BloodSpiller is definitely a DPS gain.

I will give you that, but it still doesn't seem to be as good as Scourge was.
