You’re missing Doomfist though. Sure, he doesn’t use his shotgun fist often, but when it does get used, the damage gets halved if it’s used on armor.
If you’re gonna buff shotguns, you’re still leaving out high-bullet count low damage heroes as well as energy heroes.
That’s almost half the roster effected by armor here.
It’d be significantly better to change the source of the problem rather than buff specific weaknesses. If you buff shotguns, then they’d be much stronger than normal guns, especially against melee only heroes.
Meanwhile winston, Moira, Zarya, Symmetra, Mei, Orisa, Bastion, Tracer, Sombra, Hammond, and half of Widowmaker’s kit are all being impacted by this. Most of these heroes are having their potential damage halved by armor. Others even more.
