Is "Grit" a proper name for a DRK ability?

[Brannigan]

Abandon is not the stance, it's the stacks you'll be getting while in the stance; the stance's name seems to be "Deliverance", which is very odd considering the Japanese clearly call it "Destroyer".

Japanese Defiance is Defender, so they get Defender/Destroyer. Similarly, their Infuriate is War Cry, and in the action preview video it looks like Infuriate can be used to give you 5 stacks of Abandon as well as Wrath. The loc team makes weird changes sometimes.

Back on the topic of Grit - while I think it works just fine, maybe something like "Grim Determination" would be more fitting for the dark theme.
