I doubt it. however in Halatali hard and Hullbreaker hard Gladiators and Marauders have renamed variants of the same abilities we get in the jobs for Gladiator and Warrior, Oddly Conjuer and Thaumaturge clones in Triad control use tornado and breakga. Spells I don't see used in Amdapor by the undead Whm and Blm's, although they have ancient spells we cant use either. If they do expand classes past 30, I can only see it as a means to expand the number of cross class actions for Jobs to use.
