A longer recovery for beeing hit while block-punching would be nice, still usable but pointless to abuse in a way that is just too stupid to even want to use.That seems awfully excessive to me just to remove something that's an annoyance. You'd inevitably nerf some of the slower characters like Cyrax who have to depend on things like jab baits just to keep up with the better characters.
As a sidenote: Why does Cyrax "have to depend" on jab baiting anyway..
I've played a couple of good cyrax's and they utterly destroy you without it.
