It's not my playstyle to be duelisty/brawly and I usually do number tests for combos but I've always wondered who was best at recovering from low hp for my builds if they survived. Experience said Dk's with Coagulating Blood's low hp scaling. An old and outdated test confirmed it. That test was old before Arcanist/Necrom was a thing, and I've since wondered this question again after Arcanists and the Ward change for Sorcs. Due to other threads about Sorc Shields, I'd thought I'd share the results.
But 1st what about bias/skewed results? Dk, NB, Templar, Necro all had same setup of Wretched/Talfygs to mimic the Damage in Rallying Cry/1pc Weapon/spell damage monster/Swords and oaken (not meta, just for testing)for the buffs like major sorcery. Warden and Arcanist would have plague doctor equipped for their hp scaling heals(Above setup for normal heals). And Sorc would have 1pc Mag monster and Crafty Alfiq in place of Talfygs. Jewelry was just infused Weapon/Spell damage for everyone.
Due to Oakensoul-Templar is skewed by 8% as they would have minor vitality while standing in their rune where other classes most likely wouldn't have minor vitality up.
Each class would have their respective buffs up and skills slotted like DK's minor brutality, Necro's 3% 'x' done abilities, Sorc's Aegis, Arc's Crux and their Harnessed passive. Inner light was slotted for Sorc too but not the other classes as that's not meta I believe. Merciless Resolve was used for NB instead of the stam version. No divine mundus's were on except The Lord on warden for hp.
Besides that Champion points and passives were up which meant Bastion for Sorc and Arcanist but I did not slot anything blue for all classes as I guessed meta was like reduce dmg this/reduce dmg that/Increase dmg this/Increase dmg that. I didn't think they pick the 10% single target healing done blue star but you can theorycraft new numbers after these results.
Unless specified:noncrit, and this is in a duel so Battle Spirit is up. Also on PTS so Arctic Blast was skipped.

Final comments: So it seems like Arc shield with 3 crux gave most value. I think Arc's shield is powerful because if you look at the ESO's gameplay as if it was turn based, Arc casts Runeward, you damage the 1st second shield down to 1. Arc does Damage skill and his shield is passively restored to a lesser value around ~7.5k. You use a skill to break the shield they still have. So it was pretty much like your turn got skipped if you were on the offensive. Back to defensive value, If we were to throw consistency into this argument as you aren't always having 3 crux when spamming Runeward.
Sorc's Hardened Ward would take the cake in value as it's pretty much equal to Critting every time on DK's Coagulating Blood each time at low hp. Otherwise every other burst heal would have to crit to even be close to Hardened Ward's value. Also I understand the Polar Wind number might be a shocker to some people but actual healer dedicated builds that use polar wind have even higher hp than 40k hp, but it's also possible that I could be missing something that I should've had, and even if you were to look at brawly warden builds they most likely don't use polar wind.
All in all to answer my question of who recovers best at low hp. Really anyone can hold block and use a burst heal and recover easy I just have a build setup where someone would feel compelled to roll dodge after they get stunned and eat more ticks of Radiant Oppression because of it. But it was nice to see what the difference in numbers were again and my experience would confirm that Sorc's Hardened Ward is equivalent to Dk's low hp crit Coags as I've had Sorcs eat radiant oppression at low hp and actually get out of execute range with spamming Hardened Ward majority of times.
Keep in mind again, this is champion star passives up with Bastion red perk and the 10% healing done star was not slotted for anyone, but even if it was it wouldn't really change the ranking in value between your burst heal and the 2 shield abilities.
With that, enjoy the numbers.
