Don't get me wrong, I'd much rather replace the Glare spam with a Cure spam and play whack-a-mole with my party's HP. That's the healing style I grew up with, and the one I'm used to. We both know that kind of hot take is incredibly unpopular around these parts, though.
Healing should be, in my humble opinion, a game of attrition where you are trying to manage the group's resources before the timer (aka, MP depletion) runs out. But in FFXIV, MP is plentiful and healing impactful. So the only thing left to optimize is movement and DPS.
