If green mage is the new caster job
I just hope they have a shorter cast time OR an aoe version of their spells if they give them shell, protect, bubble, and bravery to be in line with what is currently defined as green magic in the FF series.
Right now I can play "green mage" in bozja content, the buffing aspect unsurprisingly takes a lot of time. Its only alleviated by playing red mage (dualcast) and/or other people also having their lost actions be these supportive actions. As each cast of these clearly green magic buff spells is a 2.5 second cast, and is single target. Their main saving grace is that once applied, they last for 30 minutes each.
Like lets say they import the bozja lost actions as part of green mage's identity. You have queued up for a dungeon. You are then asked to wait so the green mage can buff you and the rest of the party. By default that is 40 seconds spent buffing by one party member, 20 seconds if you get two of these hypothetical green mages. Oh and if you wipe at some point? That is another 40 seconds (20 with two GM) spent buffing, again.
As green mage's core identity from past FF games, is buffing and debuffing in a way that is meant to hinder enemies and protect allies.
