You shouldn't be petty to teammates with negative K/D. This is Deadlock: you should be petty about no assists.

everyone knows you can make a comeback even if your team has way less kills and way less souls.

you can't make a comeback without assists.

don't be a douchecanoe to the player making a callout just because you see 0/5.

if they also have 16 assists, it'd be you bringing down the team by refusing to fight with the player who funneled 16 kills to teammates.
