It's become apparent that Riot does not care about the lower ranks.

It doesn't matter how well I do. I cannot get out of b5/b4. I have been as high as b1, but once I got back to the bottom, I cannot even get back to even win/loss ratio. After examining my team matching for the last 20 games, it's a miracle when my team wins at all. The matchmaking system is supposed to apply uniformly to all ranks. The problem is that lower MMR players matched with you in the Bronze range are not just unskilled. They are literally sick and tired of being stuck in bronze. They react by trolling, afk, and generally flipping the bird at ranked for their situation. The biggest problem is that there are players legitimately trying to get out of B5 and B4. And their games are dragged down by these types of players. It's nothing to do with skill down here, but all to do with attitude and frankly the system has become a caste system. I have reviewed many complaints about this system and Riot has never responded to even one. They simply ignore it. I may be bronze skill, but I enjoy the game when i am in high bronze, but the game is simply miserable in low. I don't know why I bother with this post. It's clear Riot is unsympathetic.
