So... Have you decided on what Job you'll be using for each Role for the Role quests?

[Juzjuzz]

Mele : Reaper if i like it after trying or DRG
Tank : GNB or PLD
Ranged : MCH
Caster : Smn or rdm
Healers : sage if i manadge to be decent with it.

[Hysorn]

PLD for Tanks, NIN for Melee, SMN for Magic, SCH for Healer and MCH for Ranged(Still have to level this one).

I actually completed all the ShB Role Quests on my alt first, since I had the benefit of foresight and Road to 70! Shisen did them as Gunbreaker, Astrologian, Dragoon and Red Mage! In the meantime though I've leveled Samurai up to 80 (even tho that's my main's... main) because I don't particularly like DRG, turns out, and am in the process of leveling Machinist now, now that we know they're splitting physical DPS into melee and ranged.

Tsiron's were Dark Knight, White Mage, Black Mage and Samurai. I've also now leveled Red Mage, which will probably replace BLM, and am working on Dancer. I... don't know if I really like ranged physical Jobs that much, and have basically not touched either Healer since

Tank: "Paladin" (It's my main job).

Healer: Based on my current knowledge, I'll likely go "Astrologian" unless "Sage" is more fun.

Melee DPS: "Monk" or perhaps "Ninja". Not sure yet. Although, "Reaper" seem fun.

Physical DPS: "Bard".

Caster DPS: Since almost everyone and their dogs will go "Summoner", I'll pick "Black Mage" instead.

But maybe I'll change later (except Paladin and Bard) since I'm only at the end of Stormblood. I expect what I pick for the role quests in Shadowbringer will impact who I chose in Endwalker.

[Theodric]

Tank: Paladin
Healer: Sage
Melee: Reaper
Ranged: Machinist
Caster: Red Mage

I'll get everything to max level in due time, but they're the jobs that I'll be treating as a priority this time around.

[ryouma17]

i still havent figured out which class iam taking to 90 first yet

[ItMe]

Tank: Probably Pally, but maybe DRK or War. Not sure yet.
Healer: AST
Melee: Gonna try Reaper
Physical range: MCH
Caster range: SMN

Actually, answering this question I realized (outside of tanks) I really only play one class of each role anyway.
I've levelled others, but really don't keep up with them at all. Heck, I might even stop levelling my other classes all together.

[Zeich]

Tank: DRK
Healer: WHM
Melee: MNK
Ranged: MCH
Caster: BLU SMN

...Would totally do the last on BLU if it wasn't 10-20 levels behind cap. >.>

[RitsukoSonoda]

Tank: DRK or PLD
Healer: WHM or Sage
Melee: Reaper or DRG
Ranged Physical: MCH
Caster: Explosion

Though atm I'm trying to remember if we had 5 role quests in Shadowbringers. I only recall 4 of them atm i think being broken down to tank, physical dps, magical dps, healer.

There were only 4 in ShB, yeah, likely because they were limited by the number of Ardbert's companions?
