Final Fantasy Hacktics

If there's a way to lock the blue mage class to use only the blue magic skillset, blocking the secondary A-slot (something like the chocobo rider on ffta2), you could buff/nerf the class as much as you wanted to, without the risk of breaking the game balance entirely (or having to rebalance half of the game for one job).

I'm looking for an asm that makes all calculated skills "unmimicable", and something that makes single target spells repeat its animations on every affected unit, when used by a calculator. nvm
Thanks in advance!
