As a talent it is just plain atm. The old comeback kid + what a rush combo does still exist but its garbage now that disables are more potent. You are more likely to be disabled now before you can fully make use of it.
My idea is to tie the 2 abilities into physical armor

What a rush:
no requiremnts
At 30% physical armor gain 1 turn and additional AP

Comeback kid:
no requirements
When all your physical armor is broken regain 15% of it

I fear this may completely destory perseverance's chance for usefulness but it is a step up from the current skill


Rogues are the best
