How would you fix FFVI?

[Takara]

- Limit ability of characters to learn spells; when every character but Umaro can cast Quick and Ultima, its not too intense. Not positive on how to do this.

Maybe it could be similar to FFXII: once a character gets an Esper, the others can never use it. Do you give Odin to Locke so he can benefit from the speed stat boost upon level up, or to a different character who could make more damage with Meteor?

That would also allow to make more specialized magic users. You could make Sabin more of a curative magic user or one that focuses on debuffing enemies for example; he's already a powerful fighter and had his Blitzes to rely on, he doesn't really need to learn Ultima. Give Ragnarok to Relm instead so she can learn Ultima, because little girls with the best innate Magic stat being able to wield that much power is terrifying. And then Terra learns it naturally later on, and a third character can then learn it from the Paladin Shield (make it one use only, so you can't pass the shield to another character afterwards). So you could have a maximum of 3 Ultima users ever; one natural, and up to two from learning it.

Maybe certain Espers could also be limited to certain characters for plot reasons. For example, only Terra could ever use Maduin, Shiva could be exclusive to Celes because of her affinity to ice, etc.
