I find that the games only get stressful when you get that one guy who just has to be a total ***hole because you fed a lane or missed a blitz hook. Doesn't happen often but when it does I usually just log off and play something else.
Then YOU are the worst type of player in the game, the one that manage to ruin it for 9 other people, and i honestly hope you will manage to get your account banned as soon as possible.

There is a mute button for people you dont want to listen to for a reason .
