I've been using LOLreplay to track the stats of players matched in solo queue normals. After about 50 games in solo queue, using lolking.net for stat tracking, and doing some math, it seems the matchmaker mainly cares about premades, win ratio and ranked ELO.

Common things I found from my calculations:

1) In a normal game, matchmaker will check if the person has a ranked ELO and use that to make sure players are within roughly 300-400 ELO difference. Unranked players are usually used as filler and only their win ratio seems to matter.

2) If one team has a larger number of total wins, the lower wins team will be filled with high win ratio players. If win totals are roughly the same there will be a mix of negative and positive ratio players mixed in both teams

3) If solo queuers are facing a premade, the solos will have either more total wins, higher average ELO, or higher win ratios

4) It is possible for a player with a very high win ratio to be paired with 4 losers and then pitted against an average team with only slight amounts of positive/negative in wins. I.E. 3 winners + 2 losers vs. 1 massive winner + 4 losers

5) Difference in number of wins is NOT considered AT ALL. A mage with 300 wins will still be pitted against an AD carry with 2100 wins. The gap in win ratio between those two particular players is also not considered; it only cares about the other teammates being either positive/negative in wins.

I really REALLY think they should straify the system such that number of wins and win ratio difference ARE calculated so that you at least don't get impossible opponents. That, or they start giving levels past lvl 30, because clearly some of these people are level 95+ and have no business playing against fresh lvl 30s. This would defintely reduce the amount of rage this game produces everyday. At this point the theoretical limit of 55% win rate to escape ELO hell is impossible because the system is still somewhat broken. Since you are 1 person in a 10-man coop game, you're absolutely lucky if you can squeeze 1 extra win every 20 games thru solo queue right now to escape "ELO hell". It doesn't exist, but the amount of games required to crawl out of it makes it look that way.
