Just attempted Hera-Is with my standard Kirin team (Kirin, Echidna, Sieg, Valk,Angelion). Next time I think i'll sub out Angelion for a pure green mob for extra damage against Hera-Is. I need at least 2-3 good turns to burn her down.
Mostly smooth until I got to the boss, upon which I totally messed up an easy 25x combo, and only got one activation off out of four on her. D'oh. Man, really wish I had Cu Chuu right about now..
