As you know White mage still sorely falls behind Astrologian and even the other healers. One way to solve this is by giving some identity back to White mage which was heals, heal over time and elemental buffs.

I would start by removing the hots from the other healers, especially from the barrier healers., their niche are shields. If you must give Astro a hot, put it on a 5 sec cd, but 50% stronger than their current hot.

Return mass Esuna that leaves a hot on the party.

For support a single target buff to a single player that is almost equal if more to divination 6%, for 10 secs, on a 60/120 sec cd.

Return stone skin and let it heal upon dmg break with 5 charges or so.

Fluid Aura needs to come back. Just because players didn’t use it, doesn’t mean it wasn’t used. Utility should never be removed. I used it plenty on target that the tanks missed or to leave behind an annoying mob that hits too hard to give me more time to heal the tank back up.

White mage is the healer know for damage, so return aero IV for AoE dotting. Any target that has a dot could then take increased elemental/aspected dmg from the party and self.

Or Afflatus Misery could leave a dot behind on any target it hits or increase the damage of the party for 5 secs.

I believe this would make White mage more attractive, while not making it more convoluted.
