So you looked at the base potency number on Afflatus and made the assumption that it does more damage than BLM's hardest hitting spell. You didn't even take into account Enochian's 15% damage buff (which is required to even build up to cast Xeno) but also ignore the passive damage gain BLM's get from all their spells? Afflatus will never in any situation do more damage than Xenoglossy. You clearly have no idea how either job functions.
