As mentioned under 1. Class-specific Actions, upper tier actions will be abolished in favor of scaling 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.

In my eyes that means you can simply learn the skill at the minimum level and set it on your level 50 and you'll cast it at the potency of THAT level 50 class. A Conjurer will probably be better at casting Cure than any other class at the same level due to it having higher MND and possibly traits enhancing healing potency. That and they will select materia to further enhance it.
