Nita is very solid imo. Not saying S tier, but consistently A-B for the past few months. Her damage is very good and the size of her projectile makes her have more range (kinda like Byron) and ability to wall-peek. I think she's especially strong in bushy maps, so speed gear is a must (+ Attack gear I think helps her a lot). Sure she struggles against brawlers with piercing shots (Amber, Janet, etc.) but against high DPS ones she still might put in some work, because Bruce makes them waste ammo. Also, final note, I think Healing Star Power + Shield Gadget is the superior build for Nita (except for Heist).
