Next Jobs

[CKNovel]

To narrow it down:

And now that just leaves Ninja. The only job in the game with gear to itself.
If it is a repeating cycle since Stormblood, then we are due to see another two dps as the new jobs of +1 Scouting Dps and +1 Magical Dps.
If its an adjusted cycle since Shadowbringers, then we are due to see +1 Tank and +1 Dps (Scouting or Caster)

This is well thought and logical.
I don't think SQEX would actually follow the logic but they definitely can be influenced by it.

Since they split Healers into 2 categories, it's not impossible (but unlikely) to see a 5th healer as a pure one.
Gunbreaker was added to better balance the tank trio. Until Shadowbringer, there was always one tank in the shadow.

I personally think they don't care much about the gear being shared and a Scouting gear job would be for 8.0.
I think a new caster would balance the caster trio.

Currently, Caster jobs are 2 opposite extremes (BLM/SMN) and 1 middle ground (RDM).
