Proxima has an design issue but simple fix, please kabam it's minor..
Proxima by design was supposed to be marathon content killer, with he combo fury and ramp up but Damage Caps on all those content make her not usable.
For shorter content her intercept mission is really frustrating and is a roadblock to just play her, generally ends up her dead if you get intercept mission.
I have a six star awakend proxima and I can not use her, I used pre buff unawakend Angela more than her.
She also does not sync with cosmic cavalier nodes as her design is not in line with other cosmic.
Simple fix Is she just needs her intercept mission removed which will reduce 1 prowess but adding Armour Break to her heavy and Power Gain on Sp3 will help her utility and faster cycle of specials and she is good to go.
Simple effective change, Its really frustrating to play her.
For people saying she has high skill and high payoff , I find her last choice to bring in any content I even prefer anyone else literally anyone.
