I think she is pretty bad. She’s basically a really bad Piper. If they made her shots go faster, or gave her more health, she would be a lot better. The main problem is definitely her health.
She does the damage as a Piper with the same range except her damage is consistent. Yes, her health is low but so is Piper’s. Her shots are slower because she can do so much burst potential (Kinda like Brock).
