Unlike some of the things I've seen people ask for around here, it's not for special snowflake reasons. It's because it clashes with the system in place for ability distribution, You're not going to have a BLU eating an item to learn a spell, nor eating the mob (outside of story cutscenes), much less learn spells by getting hit with them when most mob abilities only deal damage. You have to design abilities from the ground up to have effects and the synergy necessary to justify their place in the BLU spellbook.

That itself is not that difficult to put together (see my BLU writeup for an example). The issue is more ability distribution and picking skills that make sense along with a gameplay mechanic that ties everything together.
Don't even get me started on why Red Mage wouldn't work in this game either.
RDM can most definitely work.
