Please, if you are going to be childish and not play through a game, dont queue ranked.
Ranked is supposed to be a serious environment where people actually try their best to win. If you cant handle losing lane to the point where you AFK, Harass teammates and even leave the game, don't play. You ruin the game for your team and for the enemy team. We get it can be frustrating, but a team cant make a comeback if you don't actually try to. When people queue ranked they don't expect to get 5 overly positive teammates that are hellbent on winning, but they sure as hell don't want to get someone who is going to be negative through the whole game and totally ruin the fun.
