Queen is my girl. She is so nimble and Divine Judgement is an easy damage + cure. My other two are Seven and Machina, but I'm wondering if I should substitute a ranged fighter in there. I'm still trying to figure out my backups but I currently go to Nine, King, and Sice. King can really do some damage to enemies with only close-up attacks. I've also found Cater and Eight useful on occasion.
