cant reply in your post 'cause dont know why -_-", but my thoughs for BB3 are reduce the charge percent per hit, or making them use the same charge as other supers (like any console fighting game) or even add a limiter through a counter for X charges, or a cooldown like special moves
Parasoul critical mass i'd say Primed and No Egrets, for a destructive build or nice control one; and beware with those painwheels D:
Is nice to see how cerebella gets some control effects, that plus raw stats keeps her in my top rank :)
