@ RIOT Its not fun losing all the time (Matchmaking question)

Ok Im not the best player, but I felt like I got the point where I could contribute and at least was not the worst person on my team. I felt like I contributed and I would win maybe half the time, but in the last few weeks its like I am in the loser queue. The people on my team or just horrible and since I am not good that means something. I am getting matched against teams that just roll us over and over and over again. No chance. They play better individually and then actually group and team fight. They can even combo off each other.

I thought your match making system is suppose to look at me and say Hey lets pit him against a team that sucks like I do. This seemed to the case but no longer. What happened?
