I haven't played most of the other jobs, but from what I've seen and played:

Red Mage needs a damage nerf, or Black Mage needs a damage buff. I say this as someone who now mains RDM. We do far too much damage, AoE and single target. Especially compared to Black Mage, which is supposed to be the staple big damage mage. I mean watching some of the numbers go off with a black mage in the party I pretty much do the same damage per spell (slightly less), but cast them out faster because of chainspell. BLM has thunder, yeah, but i wouldn't be surprised to see RDM damage ahead of BLM by a decent margin if the numbers were compared in spite of not having a DoT.

Astrologian is fine and doesn't really need a nerf in my opinion, but I wouldn't be upset by a nerf here and there (like to Balance, perhaps a slight one to noct stance). I just want the healers to be balanced with each other.

Scholar needs buffs. Idk stats on their damage (heard they got hit hard), but AST's noct stance shields are generally better since they're instant cast and always add more shields than what was healed for with aspected benefic. SCH is supposed to be the mitigation healer. AST seems to fare better in that department at the moment (because instant cast shields that don't heavily rely on crits).

Machinist is stuck in a hole, needs buffs in general and perhaps mechanic changes to be more consistent.

Warrior could use a bit of a damage buff, but it will be a bit of a hassle to do so I think without inciting the whole "Tank Damage needs to be buffed!" and "Tanks aren't DPS" arguments.
