Roogle is right about Alma's comment about being born a man. Had she been born male, she would have trained formal battle training like the other Beoulves instead of being sent to Orbonne. The Priest (Or white mage, if you prefer) class is still a battlefield class and meant for characters that are able to go into battle. Clerics are essentially cloistered for most of their lives, and don't really have a place on the battlefield.
