I don't understand intentional feeders/rage quitters who are "sick of losing/getting bad teammates"
If you are tired of losing and having bad teammates, wouldn't that mean you **shouldn't ** feed or rage quit to make your team lose faster? This is the same application to people who try to force people to open mid if you lose one team fight and the teams are still fairly balanced in gold/objectives.
If you are announcing that you are going to troll/feed because you are sick of your team, please stop playing league of legends, or Riot should instantly ban people who announce this, there is NO reason to not ban people who intentionally throw games and parade around it.
If you get angry and upset about playing the game and throw a virtual temper tantrum and make others suffer, that's a sign you need a break from League of Legends because this game is not a substitute for therapy or the real world.
If you want to win, then the first step in winning is not intentionally throwing a game
"Never await victory"
