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

[Aleisterz]

I'd really like to see "Anathema" (synonym: ex-communication, curse by the church/papacy) rather than Grit to hit the lore based on the website thus so far. Maybe even "Heretic" based on their methods.

My perception (Heavenward isn't out yet, all speculation) is that Dark Knight is the unsung hero of revenge and brings justice against injustices by any means necessary. I know Cecil was a Dark Knight and Paladin, but Cecil showed personality changes from the two. "Betray him? Any king who'd wish for this is no king of mine." Whereas a Paladin seeks to serve in the glory of a clause to defend its people, Dark Knight compromises their righteousness by any means necessary to make things right.

What? Grit fits more especially if its gonna be the name for their tank stance ability.
