Ehm? You're saying that to someone who used to Esuna Warrior Pacification
I'm not denying Esuna's importance within it's niche, the issue is that when it's not within it's niche, it's literal dead weight. Whilst you and I might well understand the ebb and flow of it's importance, a *LOT* of people seem to struggle with that. It's not even just the importance of certain key mechanics that use it such as Dooms or Vulns, it's also really poorly explained when it's not worth casting too. I remember getting stick over a video I posted in one of the Stormblood dungeons where I didn't Esuna a poison dot off the tank despite the fact it was doing basically nothing.
Trying to twist my comment against me is missing the point here, if you're struggling to remember where it's been relevant this expansion, how do you expect a casual healer to do any better?
Besides it just seems like a no brainer to merge them to me. They are both very fast casting GCD and efficient niche restorative effects and IMO there's certainly room to add more besides. Adding more utility and value to that button should get it pressed more often which should hopefully improve the likelihood of little Timmy healer remembering to press it next time they see said dungeon doom or such. Keep it relevant in people's minds rather than it being something that gets dug out for maybe 1 or 2 key mechanics per patch cycle++
