The ranked system is broken regarding match making and MMR!
Okay so I've been stuck in Silver 1 for quite a while now. I play Irelia and Panth top along with Sej jungle. My win rate is high on all of those champs. Here's the problem, I have a really high MMR because of my stats, yet I'm getting grouped with really really bad players. My last game I had a Plat 5 Vayne on my team. That's right, I'm in Silver, she's Plat. She was one of the worst adc's I've ever played with and was the weak link on our team by far. I don't know if she was boosted or drunk but either way it screwed me. Same game - the other team has a Diamond Bard supp. Diamond? Really? I'm Silver 1, playing with Plats and against Diamonds? I'm not even allowed to que with a Diamond player. How insane is that? My duo que partner is a Silver 1 who is really good as well. So here we are getting screwed because we're matched with really low MMR high ranking players and against high MMR high ranking players. Worst part is I gain and lose the same amount of LP regardless because I'm duo que with an S1. Win or lose that's + or - 20 LP. What a shit system.
