That answer is a bit of a cop-out though, because players might be excluded for not bringing certain must-have cross class skills just the same. Or for not completing their class/job quests, which BLU\\'s spell collecting essentially is.
I dont think they can or should make BLU as a hybrid, as hybrids are hugely problematic to balance, not to mention the huge crys about BRD/MCH damage/utility tradeoff.
