Are role actions a nerf?

, so is fire IV, why have fire IV when there are people that never use it?

Fire 4 is optional in the sense that if you don't want to do high DPS, you'd never use it. Esuna doesn't have that same argument, especially in end game raids where dispellable debuffs are few and far between. Many are the times when I wished I could swap Esuna for something infinitely more useful. As of now, a rough estimate places maybe 10% of the debuffs currently in game people can remove, and of that small number, 1-2% of them are mandatory, while the remaining number won't have any appreciable impact on your dungeon run.

On another note, it's kinda funny to me to see people are defending a skill that's almost as niche as PLD's Tempered Will.
