Summoners used to be pretty versatile, too (looking at you, Eiko Carol). They could simply have Blue Mage watered down into a DPS-focused Extra Job with quests focused on tracking down monsters to learn skills from. The initial skill loadout would be hand-waved as something already recorded by the previous owner of the Soul Crystal.
