I was just in what im assuming to be a premade

In ranked, it felt like a premade 4 and we couldnt remake bc the trundle dcd, Im honestly not sure why? But anyways, my adc goe 0/9 and the support is like 0/5 and the top laner finally comes back and they all just start being toxic to me so i just muted them all but before i did they said "aww someones mad over a game" Why do people have this "I play ranked for fun only" mentality. Like should you have fun? Absolutely but at least try to win, if you DO NOT want to win go play norms and let people who want to win play competitively. I dont think ive ever been so upset by this community to where the entire team was toxic and belittling me and just running to lane to feed. Why force me to play that bc if i go afk i get reported????????????? I really only like this game because the champions are fun to play and ive never played a game so fun, ive invested time and money into this game and yet it is just another shit show because if you try to win you are a loser or a fat ugly nerd or anything else derogatory . Like i actually never understood what people gain from toxicity. "Im gonna feed then flame" Muh logic
