If I headshot someone at 10 meters with the most powerful bow in the game, the most PD available, and bodkin arrows (all loomed), I expect him to die, or at least, not to brush it off like if it's nothing. Removing the stun for very high damage entirely makes no sense, it's just another nerf. I understand that arrows that don't even deal 10% of my life shouldn't be able to stop me as long as I'm wearing a medium set of armor, but if it's a shot dealing 90% of my hp, it'd be bullshit if I can simply keep walking like if nothing happened.
