I think the main reason NRS wouldn't make his Ex knives +10 or so is that off a jump in you could do 112 Ex knives and just jail them for however many bars you have. It wouldn't be broke, but NRS doesn't like having funky looking stuff like that in game(FistiCage b121 nerfs)
And for as long as this game exists I will always complain about B1. They could've just fixed it so that it went from +2 to 0 or even -1 and since everyone has a 8 frame move it wouldn't have been a problem. But nooooooooooooooooooooooooooooooooooooooooo, that shit was made -2(not that big of a deal) and nuked in recovery(huge).
@Youphemism Well he sure as hell ain't a good zoning character I can tell you that. Also why would he have +5 knives if he wasn't a zoner? Doesn't make much sense to me.
