Third Job

So, whats the third job going to be in the expansion?

Seeker

Their primary role is going to be to seek party in Adoulin.

I think there are only two new jobs in this expansion: Geomancer and Rune Fencer.

There is literally no reason to assume there is going to be a third job.

This. There has been no announcements of a third job and at this point we have no reason to believe they have another job in the works for the expansion. It's not like they have to add 3, WoTG only added 2.

There's some test server thing where jobs were added to the index and they're like
0 NULL
1 Monk

18 Puppetmaster
19 Dancer
20 SCH
21 FIRST
22 SECOND
23 THIRD
First second and third now appear on equipment and spells, but third is on a lot of weird random ***.

But it doesn't necessarily mean anything.
