I mean is not a must, but if you like her should be enough reason to roll for her

Gameplay-wise she's arguably the best AOE Caster. Can farm with BG, can support certain allies in multi-core farming, party-wide charge is incredibly strong...

Good, yes. Not broken by any means.

Got her np5 but since she just came out recently haven't test enough. Though i did use her for this Koyo advanced quest and she absolutely destroyed it.
