Confessions of a troll/feeder/afk

I play ranked, fill, i want to win i try hard, im communicating with my team, pinging, guess what? theres 1 fkn asshole who is not listening or is not taking the game seriously, as the game goes on we are throwing and eventually lose, now im fkn pissed and next game in pre-chat i tell them that im fkn throwing the game, enjoy ur fkn loss and i either go afk for a few minutes and then feed or push another allies lane to be an a-hole. ive done this many times for REVENGE, this will NEVER stop, RIOT and nobody has the power to stop this, you get a bad game, you want revenge, theres no changing that, but... if you have a good personality and ur humble, u take the loss and move on and help your team, how did i change? i spectated friends that are in diamond and asked for advice, and they tell me to focus on yourself, focus on your mistakes, and i realized im the horrible player, yes i didnt feed, but i didnt focus on objectives or helped a struggling lane, it's your fault someway or another if you lose, this is a TEAM game so that's what you must focus on
