From what I have read so far, the names dropped are : Reaper, Necromancer, Assassin, Beastmaster, Templar, Corsair, Hunter.

Another theory I have could be related to Bozja.

For the healers, we have the Essence of the Elder which is called Essence du Sage in French.
So maybe, Duelist which is Duelliste in French could be the name of the next melee job.
But a Duelist with a Scyth seems weird, I don't know.
