I'm pretty sure there isn't gonna be a summoner job. If you pay attention to the plot it's moving in the direction of us gaining the ability to summon in order to fight the empire. Everyone who walks the path of the twelve has the ability to summon. Stop thinking oldschool and start thinking Guardian Force. Just thought I'd point that out since I notice alot of people pining for full summoner job and in my mind everyone having thier own avatar is a hell of alot cooler then any pet jorb.
