I wanna to point out a little idea that was floating in my mind that is the Alchemist's Alchemy.
When you choose a skill, then you can choose another one and comboine them, to create a new powerful skill.
Every skill has a rank, that could be 1 , 2, 3, S, SS, SSS (or 3S).
You can use and combine only skill from 1 to 3, to create skill from 2 to 3S.
That does not means that a 3ranked skill + 3 ranked skill = powerfull and unnatural skill
Use logic: if you combine Firaga with Tsunami what do you think it could happens?
The created skill stay in you skill list untill the end of the battle and they can be used for all the battletime long:)
What do you think about it?
