I'm done I swear Im done

After climbing from B5 to my promos for B1 I have gotten a looooong string of just bad bad teams. I mean bad. People who AFK, just feed, people who throw the game when we are 8k gold ahead because they refuse to group and take objectives. Heimer who just sits top all game and overextends, and wont help the team cause all team fights to be 4 on 5. I'm just done Riot. I like this game but matchmaker is broken. I get one decent team in 10 games. I went from a 53% win rate to 49%. My ability hasn't changed. I almost always win lane only to have my teammates just feed like hell and throw the game. Game after game after game. WTH MATCHMAKER!?!?!?! I'm 6/1 zed, just owning my lane and ganking fools. I get my turret down, we are way ahead, and then teemo decides "hey I'll give the enemy yas 10 kills" I MEAN WTH! Every game! EVERY DAMNED GAME! This game SUX! matchmaker SUX! There is no way to climb in ranked because for 9/10 games y6ou are paired with players that are so bad it IMPOSSIBLE to win! Completely one sided games. I'm 11/0 on Akali. Mid game my team decides "hey lets just solo push lanes and wander the jg and die repeatedly". I cannot out kill their feed. So So frustrating. I reinstalled this game today to give it one more shot, but I'm threw. So sick of toxic feeding bad teams over and over and over. I can't do it. Matchmaker can suck a fat one. Everytime I get to promos you give me the WORST players I've ever seen EVER! I swear they are all that secretary of education of the movie Idiocracy! Just drooling on their keyboards in a dark corner somewhere. This whole ranked system is broken!
