[Autumn]

While I see why you wouldn't want to give capture certain defeat, I think its also not comparable to checkmate, given its low hitrate and damage. Nailing the death attack with it is fairly difficult and therefore it would never be a replacement for checkmate.

I think its difficult enough to be "fair" in that regard, alas I am indifferent towards it.

I never exactly implied it would be replacing checkmate, I think Certain Defeat is the strongest aspect of it.
