The initial idea was, a tank defensive that reduces the tank's damage in some way in order to use a defensive action.
The initial idea... from what post? The first post merely asks a spitball question about tank stances, be they for defense or enmity. The second, mine, immediately points out that tank stances are NOT required for decisions in of output (between greater offense or sustain) and that, especially if healers' contexts weren't so abysmal right now, we could easily see situations where at-cost flexible options to mitigation see optimal use even without that being the difference between life and death in that moment.
There's no insistence on CD -> take damage debuff -> defensive action unlocked.
Note that "sustain" is anything that keeps you and/or allies alive for longer.
In any fight won by reducing the enemy's HP to 0 (so, every fight in XIV and most fights in every other MMO), its value is ultimately the rDPS difference you get for spending that much less time dead or under Weakened/Brink of Death.- By and large, in the present context, most of each healer's sustain is "flat", not timing-sensitive. The total amount of damage negation or restoration rarely vary with incoming (Exaltation) or past (Macrocosmos) damage intake. And rarely would --not that either see use-- a Regen create less total effective potency than a Cure II, because we aren't so stressed by incoming damage that we'd ever have to preempt it with something that may eventually overheal nor that we'd have to forgo the over-time option with greater maximum potency. As such, it ends up extremely simple.
- On the other hand, especially until Endwalker, the majority of tank sustain has been timing-sensitive; affecting a dense period of damage intake with % damage reduction or % damage recovery (a Death Strike -style action) is hugely more valuable than affecting a shallow period of damage intake because the sustain that most tank actions produce is not only potentially bottlenecked by but even scales with that context.
- Unlike flat actions (just plain healing, especially where it's not bottlenecked or complicated in any way), time-sensitive actions can see optimal use some of the time even while being unnecessary at others.
