Casters are ranged DPS making the total of those not counting BLU as 6 and the most saturated role in game.

If you're going to split hairs and call caster and aiming separate then you have to do the same for melee dps making it 2,2,1. The 1 being scouting and all 3 being lower than both types of ranged DPS. There's also the argument that NIN is a hybrid DPS rather than a dedicated physical one.

Then there's also those comments they made about whatever jobs come next will be something new to the franchise implying they won't be grabbing jobs from previous FF titles. Though that raises a question of whether or not other SE titles are fair game. Other titles with job systems I can immediately recall are the Bravely Default series, Dragon Quest series, and Harvestella.
If we are going to split hairs do all the melee have different looking “Role Actions” tabs. Because casters and physical ranged dps do.
