Okay, so for 1.20 patch their getting rid of higher tier actions e.g, (Fire III, II) to scale the potency of the base action according to level. The effectiveness and MP cost of the action will be dependent upon the level of your current class.

This is a great idea, but will the animations be changed as you level up and use stronger potency's of say Fire

There need to be more interesting changes to the animations as that scales up.
