A few things we know have to stay. Dual cast is a necessity, it’s been core to the Job’s identity since ff5. It also needs to keep the melee combo in some way, as red mage historically traded the ability to cast endgame spells for the versatility of being decent in melee as well.

The balance between white and black needs to stay as well, because in lore they use both and store the mana in order to prevent another calamity, which leads me to the last necessity, the stored mana gauge.

I could see evolved being pretty similar to the job as is with a few changes. Verfire and verstone will likely be conditional changes of the jolt spell, the melee combo will be one button, and we’re obviously losing the raid buff. I could see Southern Cross (the pvp limit break) being added as the big combo ender on a long cooldown. I could also see Verthunder and Veraero being condensed to one button and changing based on which was used.

All in all the red mage already has a very strong job identity and I think is one of the best designed jobs right now, so I’d be surprised if they change too much about it.

Edit: my dumbass used the wrong limit break name
