It’s a definite improvement but doesn’t really bring her into the meta for me. Rather than a parry I’d have liked the ‘release’ of shock charges to be on a light into a special so that you have full control. This and a faster charge time would have made me R3 mine. As it is, I think she may suffer from Thor syndrome, only being really viable in a fight she can go sp3-2-3 etc.
For those of you concerned with Nebula's weak block proficiency, fret not. Just get Canada on the phone and they'll send their boy Guardian to fix that problem.
