We already know that the new unseen job is a ranged caster dps, so I don’t imagine it’d be Green Mage. I mean, for one thing, it’d be kinda weird to have a job with ‘Green’ in its name but it’s in the red role section (dps) instead of, well, the green one lol. Plus, ‘Green Mage’ as others have pointed out is a buff/debuff class traditionally in FF, which literally cannot exist in ffxiv under any circumstances (which makes AST seem like a bit of a joke but that’s for another thread lol)
