How would you fix FFVI?

[Roogle]

If people want to get rid of "everyone can learn all spells", I think a good example to follow would be FF XII International's Zodiac Job system. Pick one class that can only learn a certain amount of skills and spells, and you're stuck with it for the rest of the game. That'll keep the magic pools unique. How many characters did VI have again? 14? You could asign each of them a zodiac job (with two that will end up re-using an already used job by another character) and have a fully unique cast with a wide variety of magic lists.

They could handle magic similar to equipment. For example, Espers can only teach certain characters certain spells. Suppose that only Shadow and Gau could learn Vanish, giving you more incentive to use them for that specific spell. Spells could be tailored to fit specific characters skillsets and build on them rather than detract from them.

Thought of an idea for making Gau less grind-y: Allow him to learn rages if you leave him on the Veldt.

Example:
He leaps into a monster group. You leave the Veldt and do whatever. Based on how long you've gone without him (probably based AP, similar to Terra's Trance), when you get him back, he'll have learned a certain number of rages (of the learnable ones by that point in the game), with some randomness factored in.

When I play the game, I simply put in a code to allow Gau to use all of his rages from the start. Obviously, I try to stick to ones that I have encountered so far so that he doesn't become overpowered. Maybe a system that allows you to easily gain access to Rages, but you can only use a certain amount before he has to go back to the Veldt and recharge or something? It's a difficult question.
