Ok, my idea for Blue Mage is this. Class, Magus, dps/support (IE like Bard). Some One Handed Scimitars, Some attack blade skills and a series of "Enchant Weapon with Element/Effect" skills. Blue Mage, no "Learn" as that just won't work here. Instead make an attack based on each of the beastmen races, no necessarily attacks they actually know, instead sort of skills that embody the race. Ifrit's own grand a momentary boost to attack power, Garudia's children grant an AoE sleep spell, exc. Maybe not that but like it you know.
