WAR- Defender
MNK- Final Heaven
DRG- Holy Breath/Super Jump
BRD- Getting Ranged Limit breaks, so maybe Piercing Shot/Sidewinder/Empyreal Arrow
PLD- Probably inherent current LB3
BLM- Inheriting Meteor obviously
SMN- Megaflare!
SCH- Embrava
WHM- Inherent Pulse of Life
NIN - Mijin Gakure, without the death, or one of their katana skills from FFXI
