How would this work with Sombra’s hack and Mei’s freeze?
Wouldn’t this also not make him invulnerable in their ultimates?
I rather see some knockback resistance when Reinhardt is using his shield instead of immunity to stuns.
But to be honest, I don’t think he needs a buff. At least not a massive one.
His pickrate is still healthy in all ranks and he has a positive winrate.
Small note:
Dva and orisa have a resistance to knockbacks when they are shooting, but this is confirmed to be a bug:
