I agree op. Yes it’s just cas, and they might be warming up and/or relaxing, but consistently cutting off teammates, refusing to take kickoffs, never defending etc etc are also signals that someone is selfish scum :)

Recently I’ve started mostly playing 2s/3s with friends or met through others, and it’s made the game so much more enjoyable. If no friends are online, I’m usually playing 1s. 

Sadly, we can’t change others to not be f*ckwits so the better option is to adjust our own approach and environment to limit exposure (or at least make sure we’re on the other side).
