More damage is always better, it's not as high as your main dps, but it's significant enough that it could brick your run when trying to rush the missile phase (I had a lot of very close call in tor). Not saying to rush getting her eleph, but you'll need it eventually.

If you're using her for PVP, 3* is definitely not fine. And she may need some survivability for Hod.

Though I agree that they're not going to be your highest priority until much later.
