Instead of 30 regen per sec after 3 sec of not taking damage, it should be 2.5 regen per sec for every 25 max shield health the character has, this way it can help characters that need the sustain. Like Domina could have a weaker barrier since her shield health would help keep her up in combat.
We already have the out of combat self-heal global passive, so makes sense to make Shield Health help during combat.
You don’t get the point I guess
Sig Zarya and domina have defensive abilities that can buy them enough time to trigger the passive (though Zarya must go to cover), meaning they are tanks that passively sustain themselves quietly for much of the game.
Zen and sym are heros who require major support and resources to function due to their kits, so they have built in reward for using cover or playing careful positioning.
The flying dos have it so they can mini sustain because many supports can’t help them.
Then there is Juno who absolutely should not have shields for any reason and they just wanted to make sure she had 0 real weaknesses (and apparently every support has to be able to heal themselves which wasn’t true until sub role passives came into play but I guess it’s true now, still, she shouldn’t have survivor healing * shield healing)
Anyway, if shield got reworked, I would instead just buff it to “as long as shields are intact, an individual instance of damage can’t bleed over to health”, so you could imagine a widow head shot failing to one shot because it deals shield damage and the excess damage dealt is lost. This would provide a level of survival utility many shield heros desperately need due to their kits.
Sigma can be shot from the side/back or be getting melee hit so his Shield Health regen will never activate. Making it like I suggested would make it’s use much more consistent across the board, and they can always adjust how much regen they get by changing the max shield health.
Zen and Sym have no in-combat sustain, something they could benefit from to help them not die extremely quick into the fight from getting pressured.
And since the flying DPS can’t usually get heals, giving them a little shield health for some level of in-combat sustain would be a good tuning knob to help balance them with.
Having to wait 3 sec’s for current shield regen to kick in rewards heavy barrier use and taking cover against ranged damage, and basically will never kick in during a brawl. I think evening out it’s use makes a lot of sense, worse when hiding behind barriers/cover against poke and more consistently useful in general if it were changed to constantly regen.
Would only be good against burst damage heroes, basically useless against any kind of sustained pressure.
