Kinda bored. So here's something. What is does your character say when they do their LB3?
Doesn't have to be something you actually macro out or anything. It's just a big giant move like that is deserving of some cool quip of some kind.

My examples:

AST: Oh, starlight! Flare up now like the morning sun, and guide us through the night!
SMN: Mine is the power that ended an Era. What hope do -you- have?
SCH: Sorry if you thought you were winning. I'm afraid you've just fallen for my gambit.
DRG: Song of Anger and Sorrow! Bend to my will and destroy those who stand against me!
