honestly, the only use I've noticed out of Form Shift is using the ability pre-battle.

before a battle i just Form Shift 3 to 2 times to get to get to the Coeurl or Raptor stance, and the first hit on an enemy instantly activates Greased Lightning(Coeurl) and whatever status effect depending on the attack.

is this the only use for the ability, or is there any other way to utilize the ability?
