Simple Solution to BLU

[Amused]

I've always imagined, and would much rather BLU function with abilities that count as a tier of enemy abilities/spells. With that ability you can select from a batch of abilities/spells that you've learned that fall within that tier. This is how every BLU ability would work, with more powerful abilities being reserved to the higher tier.

Not really digging the multiple soul crystals for each job thing. Seems like an awkward way to implement things.
