From what I understand is ACN is debuff and summon... Scholar is healer nuker they could have told us the job but not released what class it comes from. I'm betting oracle or sage is its class and there are alot of names for books they don't have to all be grimiores. THM and CNJ weapons are all a different weapon type but are similar. Yoshi also said that there will be a new healer type class and job ACN isn't going to heal.
