Honestly that's a hard question to answer. Will she heal efficiently in high deficit? Fuck no. Does her heal matter in normal stages or low deficit? It seems to be the case, she seems to heal a decent amount if your tanks actually tank for a while.
At the same time, for most of the clan raid stages you didn't need healing and for the last 2, she probably doesn't work because her heal is on 2 targets only. It's a mixed bag but I expect her to perform really well in a marksman team to pump dmg into a solo raid.
Threw her into a few random stages with a basic bitch rotation and her healing numbers were consistently around double of Acappella's.
