Honestly, I'm not against it.
Being undercapped is the simple most frustrating thing about games like this, I spent most of my time leveling overcapped simply to make sure I don't miss, because missing is anti-fun.
At the very least, I'd like to see it given a secondary effect so that being overcapped isn't a total waste.
The crit idea is nice, if only because it makes excess accuracy not worthless.
I wouldn't mind having them remove it and replace it with more interesting stats.
A crit multiplier stat could be fun.
