Job Wheel!

[Rustyhagun]

I hope this is a secret reveal...but it's probably just Arcanist.

Would be silly on the artist part if it were arcanist, as the depiction of the foreground art work, depicts only the FF14 Jobs(There is a theme going on there). Second that outfit has nothing to do with arcanist/summoner, that is a Scholar AF outfit from FFXI, lets not insult the artist intelligence.
3rd Yoshi and team have not shown anything on arcanist yet and they could have easily switch its weapon from a book to something else and just added a scholar Job(what its class will be remains to be seen)

Not sure why everyone thinks Yoshi and Team would not be working on new class/jobs for this game. They do have a team dedicated just for that... This is hype and its working!
