what the deal is bout fusion spells would be castin two spells to make one spell you cant cast nomrally like since sch cant use AM's fusion would be like Fire V + Thunder V = Burst I or somethin like that and combinin two debuff spells to make Demi or two spells to create Ultima so blu and blm wouldnt lose out with Fusion spells to create another blm can also probably Magic burst same with ws skill chains just like blu can do the same
