What's next for new jobs after Endwalker.

[Mugear_bahamut]

So let’s think about it this way.
During the recent live letter, Yoshi-P said that they won’t be adding 2 DPS jobs at once, as they did in Stormblood.
He also mentioned they’re not adding 3 jobs at once like in Heavensward.

There are currently:

4 Tanks: 2 MT 2 OT
4 Healers: 2 Pure 2 Barrier
5 Melee: 2 Striking 2 Maiming 1 Scouting
3 Ranged: 2 Support 1 Selfish
4 Casters: 2 Crit-based 2 SpS-based(One is limited)

There are at least 5 more expansions in XIV’s main story.
They also have a pattern of adding a healer or tank at intervals.
If you think of them pairing a DPS with a Healer or Tank, it would go like this:

(The DPS slots are just examples according to their released order up until now)

7.0 OT Tank, Scouting
8.0 Pure Healer, Striking
9.0 MT Tank, Selfish Ranged
10.0 Barrier Healer, Maiming
11.0 Scouting, Blue Mage is a normal Job(Assuming it’s the Whalaqee expansion)

We end up with:

6 Tanks: 3 MT 3 OT
6 Healers: 3 Pure 3 Barrier
9 Melee: 3 Striking 3 Maiming 3 Scouting
4 Ranged: 2 Support 2 Selfish
4 Casters: 2 Crit-based 2 SpS-based
