7.0 We need new caster and ranged dps balance the score

[Beddict]

No we do not. Ranged jobs are actually the most prevalent role right now if you consider that casters and physical ranged are actually subsets of that role.

• 4 tanks (PLD, WAR, DRK and GNB)
• 4 healers (WHM, SCH, AST and SGE)
• 5 melee (DRG, RPR, MNK, SAM and NIN)
• 6 ranged (BRD, MCH and DNC + BLM, RDM and SMN)

I expect the limit on full jobs is something like 20 total jobs as we are already seeing them run into the limit on their ability to create new weapons for 17 jobs. We do not really need any more casters or physical ranged full jobs. At most we might see 1 more melee job .

To further back up what Grimoire-M is saying, Yoshi-P talked about the Roles prior to Shadowbringers. From Letter from the Producer, LXII (05/09/2019):

Only Two Physical Ranged DPS Jobs Are Currently Implemented

As of Stormblood, there are three tank, three healer, four melee DPS, three magical ranged DPS, and two physical ranged DPS jobs. We believe that there is value in adding another physical ranged DPS to improve the balance of available roles, and so we decided to use one of our two new jobs to fill this need.

While the community may lump Physical Ranged and Casters into one category, Yoshi-P and the dev team clearly do not.
