Job Wheel!

[Quesse]

I don't think that's actually 'Scholar', but just a depiction of Arcanist (note the book held in her hands which has been confirmed already to be ACN's weapon).

That pic has already caused a major stir on another certain forum which I won't go into, but I think it's safe to say that is not a sneak peak of a hypothetical Scholar class being added into the game.

You're wrong. All the other pics are of JOBS. So its not a class depicted but the scholar JOB.
