Healers need an overhaul

[Aravell]

First, get rid of most (ramping-to-)OHKO mechanics, replacing them with some way for healers to actually undo them, ideally without relying on Esuna. It's fine if the ally would die exactly 3s later from a non-global DoT tick if not healed in time (and to require significant healing thereafter), or even for survival to cost a spammable but at-hefty-MP cost (especially if, say, lower %MP = lower effective potency to attack spells as well, giving those oGCDs a slight offensive opportunity cost more immediately) eHP-increasing tool to be cast on them just before impact, but there must be something that the healer can do to prevent that death.

This is something that P10S does right. If someone gets hit by the chain tower, it can be fixed with Esuna and a quick top up. If someone mistakenly walks into the poison puddle, you can keep them alive with concentrated heals.

I agree that we could use a lot less instant death mechanics in savage and extremes, more recoverable situations would allow a skilled healer to fix bad situations.

EDIT:

That said, I don't honestly even care that, well, anything gets damage-refunded. Any "damage-refunding" is, in balance, almost certainly all being pulled from the same budget of expected potency-per-minute anyways (the more 'refunded' potency, the less potency per actual attack to compensate).

Honestly, I'd love to return to the ARR/HW era where there was little to no free healing, where you had to work in tandem with your cohealer to truly excel, not merely work around them. But I think that would be a bit too drastic of a change from what we have right now, so I advocate a half-measure in the form of damage refunding.
