matchmaking

matchmaking in league of legends is terrible, i feed less than 5% of my games and lose 75% of them, my team mates don't know how to play well enough to win a game, today i played 6 games and fed one of them, i lost 5 of them and got demoted, i feel like i should be playing with people of similar skill level to my own sometimes there is someone on the other team that feeds and then ends up carried to a win, that has not happened to me in a months i am aware that i sound like a noob who is bad and expects to get carried but if you think that then you probably haven't experienced this before
