Some Dark Knight 4.0 feedback

[Chrono_Rising]

It is a minor dps loss to use TBN to get off a bloodspiller. The 2400 mp is better spent on dark arts giving 140 potency to one combo over spending the same mp to get a bloodspiller when in pure dps mode. The difference is minor and assumes the shield breaks. If it doesn't break, then it is a major dps loss since you are out the mp and the blood.

Even better would be if bloodspiller was off the gcd. Then bloodspiller generated by any means would be a dps gain. And would mean we would prioritize shield usage whenever it was up. But it's not and they probably won't make that change.
