It sounds wonderful, but so does any expansion of the armory system. >.< I think something with FFT style classes/jobs makes a lot of sense. I would think it would work kind of like: rank up set amount of classes to pre determined rank > unlock quest to become a new job > complete quest and gain access to said job.

An loose example would be like: Requirement to unlock Arcanist Quest would be rank 30 Conjurer and rank 30 Thaumaturge. Then you complete that quest in order to unlock the Arcanist class for you to use. (Or maybe a series of quests. ^-^)
