How about a non-support ranged dps?

[Shurrikhan]

Indeed. And honestly one of the ways they could tune a "non-support" ranged DPS would be for it to have less utility than the others (that kind of balancing already sort of exists for MNK, which has higher theoretical DPS but less useful utility, and NIN which has lower personal DPS but much higher utility).

Such a DPS would likely compete with BLM/SMN for party slot, which might cause concern due to the fact that a lot of fights "require" magic damage (original T4 and T11 for instance), but given that Final Fantasy has potential to add melee casters (either Red Mage or Blue Mage), there are ways to prevent it from being a problem.

If Ranger/Sniper/Marksman, ammo types would be another, though perhaps gimmicky, workaround.
