With the nature of some weapons, it would allow some styles to get totally blown away.
Same for triggers based off the opponent's fighting style. That could also lead to a fight where glads keep just changing strategy in reaction to their opponent's strategy change
I know I wouldnt use them, but I think triggers like the following would be good.
I/My opponent is stunned
I/My opponent has an offensive bonus
I/My opponent has an offensive penalty
I/My opponent has an defensive bonus
I/My opponent has an defensive penalty
