So, something kind of like what BLU has going on in that you have different actions that do the same thing but have different elements/animations? I've always liked that aspect, it allowed for more creative combinations in your spell loadout. I would love something like that for all other jobs, where you can customize the animations/theme but it's purely aesthetic so nobody would need to be hounded about "optimization". It would add flavor and make the way you play the class feel a little more "unique".
