Ah, I think I misled you with crappy writing--I'm fine with Sybilla, it's Clissa that feels like a bit of a tease right now. I was mentally comparing Clissa to Claudia because they both dabble in true damage but I suppose Clissa's far superior when you remember to factor in her bulk and attack speed advantage. I'm just being a spoiled brat right now because her Awakened skill is so much better than Heal IV.
