Fixing Every Healer Job

This would depend entirely on mobs not progressing towards auto-attacks or future special attacks while stunned. If player behavior is anything to go by, they likely progress towards both. The stun would then merely delay readied auto-attacks from being cast, much like downtime does for us.

I.e., if one is stunned for 2 seconds with only 1.5 seconds left until auto-attack, they've lost .5s of autos; however, if they're stunned for 2 seconds and still had 2+ seconds left until their next auto-attack, their damage won't have decreased at all.

The same interaction would occur with special attacks, most noticeably the instant casts among them.

tl;dr:
Holy's total stun duration would need to have no gaps for it to provide even 7 seconds of complete damage mitigation (technically, still short of that, as any time until next auto eclipsed by the stun would not be affected).

On average, Holy likely instead tends to net about 3 seconds of trimmed autos from mobs being unable to use capped/readied auto-attacks, and briefly delayed castless specials, across the spam. Its utility value is both generally greatly overestimated and appears to come at cost elsewhere in the toolkit (in terms of bankability and modularity of free heals).

I think you're downplaying it a bit, being able to halt the entire pull's damage output for any length of time is insanely good mitigation. It's difficult to tell just how long the mobs stop for, but from experimenting it seems to be closer to seven than three seconds. Not to mention the bulk of damage naturally coming at the start of pulls when all the mobs are still alive.

Tetra, bene, assize, asylum, liturgy for free heals, 2x divine benison, aquaveil and temperance for free mit. Pulls usually last about 40s-1m so you're usually going to have at least tetra and assize up each time.

It's difficult to tell just how long the mobs stop for, but from experimenting it seems to be closer to seven than three seconds.

It has a cumulative stun time of 7 seconds, yes, but that is irrelevant to the cumulative full mitigation time unless, during time stunned, the given mob generates no offensive resource / do not progress towards any further offensive events. That does not appear to be the case.

Instead, a stun only appears to prevent capped/readied auto-attack / special attack timers from going off, not from progressing their timers.

Tetra (700p), bene, assize (400p), asylum (800p), liturgy for free heals, 2x divine benison (500p), aquaveil (15%) and temperance (10%) for free mit. Pulls usually last about 40s-1m so you're usually going to have at least tetra and assize up each time.

As compared to Essential Dignity (up to 900p), Collective Unconscious (500p), Celestial Opposition (1000p), Earthly Star (720p), Lady of Crowns (400p), Celestial Intersection (600p), Horoscope, Exaltation (10% + 500p), and Macrocosmos (15s, 25%), and Neutral Sect into pre-shield (750p).

Again, the claim was merely that the other healers have a bit more potency and fluidity to make up for Holy's full mitigation time, which is, again, less than the total stun time Holy provides.
