I was just thinking that if SE doesn't see blue mage as an implementable class in 14 due to the nature of learning enemy skills, they could easily just make them all learnable from quests like the special abilities for jobs. each quest would basically be "go fight this special event monster or X number of regular monsters of a certain type", and then you report back for a new skill learned from the monster you defeated. as for blue mage not fitting into the holy trinity, due to it's wide array of different types of abilities, it could maybe lock into a certain spot of it's choosing, which would lock certain abilities, giving them a specific role (unchangeable at any time gear cannot be changed, i.e. mid-battle and in dungeons, etc.) if it equipped spells like in ffxi, it could be classified as healer, tank, or dps depending on what kind of spells it has the majority of, and take that spot in the duty finder. for example, if you equip more than 1/2 healing spells, you queue as healer.
