She is a great hero with really bad speed who is great to have when all goes well but after your team loses a couple of heroes she's very squishy. She's solid in GW due to the self healing and team heal on special crit (RNG).
In a QGJ led team, she perks up a bit more but is destroyed by the sith so she won't get much use for now in arena. I could also see her doing decently in a Jedi/NS team.
TLDR: she's too slow and subject to the current anti-Jedi meta.
