So, on servers that have friendly fire on, if I see a teammate near me go into slow death, I usually whip out my Nagant/Luger and put a bullet in his brain. Much less harrowing than dying a slow death by bleeding I'd imagine. I'm still penalized for this however. IMO if you shoot a teammate who has gone into slow death you shouldn't be penalized. It's a mercy for the player (who doesn't have to basically have everything but their mouse taken away from them for several seconds) and for the avatar, who no longer dies in a drawn out fashion but quickly and (i would imagine) relatively painlessly.
P.S: I am by no means saying I dislike the slow death mechanic- I love it and I think it adds to the game.
