Bring back the traditional UI for battles:

Attack (switch targets or toggle Auto attack on-off?)
Magic
Ability
Weapon Skill
Item

This is the Final fantasy UI, it's always been like this and should never change for any reason, you're still using it in FF action-style RPG and it works perfectly (Vers XIII, type-0).
Whitout that UI I (we?) will never feel like doing Final Fantasy battles.

Sorry for my bad english
