The New Job (If Any) Added In 7.0 Will Likely Be Scouting Melee DPS

[Seraphor]

I doubt we will be getting any new Tanks or Healers, period.
It was clearly a struggle for them to come up with the job design for Sage as it was, coming up with a fifth healer job mechanic doesn't seem likely. Plus we are looking at 20+ jobs now, it's getting very hard for them to manage.

We know from interviews that their process for designing and implementing new jobs is as follows:

1. Mechanics. Do we have a fun and interesting mechanic to base a job around? This is by far the most important. They need to have the mechanics down first before they can begin to fit a job around it. They're likely workshopping multiple job mechanics at any given time.

2. What's needed? What role hasn't had anything for the longest time? This is fairly nebulous, because by design, roles can be allocated in any numbers. If you look at roles as Tanks/Healers/DPS, then we're due a Tank. But if you look at roles as Tanks/Healers/Melee/Phys/Ranged/Casters, then we're due a Caster. And you can go even further to Fending/Healing/Maiming/Slaying/Scouting/Aiming/Casting, which brings us around to Scouting... and we know they can use gear sets as justification, as this was their reasoning behind Reaper. The different role paradigms are likely intentionally flexible, to allow them to target the role that they deem is in need the most, without having to be constrained by a singular definitive timeline.

3. Job fantasy. What previous FF job class fits this mechanic/role? How does it fit into the games lore? Still important, but it is the last step and the lowest priority.

There may have been outcry at first when SB launched with no Tanks or Healers, but this was the games second expansion, no pattern had been developed yet, and our one and only expansion so far had given us 1 of each role. We now have four of each role, and I don't think anyone can claim we have a shortage of Tank or Healer jobs right now. Four options is sufficient. By comparison, we only have three Caster DPS and Physical Ranged jobs.
We are simply not in need of any Tank or Healer jobs right now. All the jobs/roles currently in need by the combined factors of 'number of jobs in that role' and 'length of time passed since their last iteration', are DPS jobs.

Now if I was being optimistic, I would suggest that the pattern for new jobs over the next 3 expansions would look something like this:
7.0: Scouting and Caster
8.0: Tank and Phys Ranged
9.0: Healer and Melee

But given how we're rapidly reaching unmanageable numbers of jobs in this game, with each expansion giving us less and less content per job due to the exponentially increasing workload, I wouldn't be at all surprised if our new job trajectory looked like this:
7.0: Caster
8.0: Scouting
9.0: Phys Ranged

At which point we'd likely be done for new jobs entirely, and the game would be on maintenance mode like XI.
