that might be the wrong word for it...but I've played her, love her, got her to 60, etc, but little things, mainly the lack of a free run power, just make her not hold up well...but I was thinking, what does she really NEED to break back out? She doesn't feel like she actually needs much of a damage buff, just minor changes here and there...and of course, my tiny little personal list of what I feel is all she needs:
Fast Track: 1 rank, free, otherwise no changes. Same as their standard for other characters.
Opening Statement: Needs movement/geometry cleanup. More recent heroes like Black Cat with similar 'forward leap' moves are able to clear terrain on a much more 'consistant' basis, if that makes any sense...hers feels like it's obeying 'too many' laws of physics, as it were, in comparison.
Several moves: Some form of 'protection' against getting knocked out of an animation and losing the cooldown/etc without getting the result. This might be asking too muck for minor work, it seems to happen more often with Bar Exam than anything.
