DRK is going to be Nerfed in Stormblood

[Yasminou]

So I was looking over the drk potencies and I noticed bloodspiller has a higher potency with DA and grit on. Is the potency higher in grit vs non grit when you factor in the tank stance damage penalty?

When the 20% penalty is factored, the potency increase is nullified. In fact, they could have worded this as for Inner Beast / Steel Cyclone "Ignores the 25% damage penalty inflicted by Defiance."
