Now that the uprising gamemode is back, I noticed something. Even heros that can't deal headshot damage still deal critical damage to the large bombs (detonators) that drop to blow up the payload (for example bastion turret form).
However, how does this apply to ultimates such as high noon, meis' and other non-projectile/hitscan based hero ability (and junkrats'). What hero's can still not deal "critical" damage to the detonator?
