I know DoTs have been starting to phase out, but I think Red Mage might really benefit from some sort of DoT or over time effect that acts somewhat like Comfort Zone for the mana gauge. That is, it costs a certain amount to apply but then slowly pays for itself from uptime, allowing you to then engage in melee slightly more often. Perhaps an en-element/saber effect onto their weapon's auto attacks? It would create an interesting dynamic for Red Mage to keep in melee range while the effect is active and timed with Embolden/not Displacement and also give manafication timing some more complexity.

This would be a selfish gain and not necessarily party utility, I suppose. I'm not so sure I like the idea of such strong buffs tied to the mana meter, and also while there's still conflict over Verraise's power.
