First of all, I invite you to look at my previous posts in the thread. I am fully aware, as a rather avid chess player, that the system was invented by a man named Arpad Elo and that League of Legends uses a modified version of it. I don't see how you thought posting this was of any help at all.
Second of all, I also invite you to think about how Elo works. If I have 10 players with 1k Elo, 5 of which started at 1.5k Elo and 5 of which started at 500 Elo, you're going to quickly realize that the system believes they are of the same skill level (1k Elo). Yet if you look at their win losses, it would be something like 75% compared to 25%. The matchmaking system doesn't take win/loss into account because there's no REASON to. Elo is a measure of your ability to win games - and win ratio has nothing to do with that.
Let's take my normal games win/loss, for example:
I have 1257 wins and 1115 losses. This means that I have 142 wins over losses. If we assumed that each win gave roughly 12 Elo, and I started at 1200 Elo, this would put my estimated Elo around 2900. However, if you look at my win:loss ratio, I get just under 53% win rate. Now clearly my Elo is not 2900, or I'd be a pro player right now, but the more games you play, the more your win/loss gravitates towards 50%.
There are pro players with a far lower win rate than your 66%. Dyrus, for example, had a 54% win rate over 1750 games (that's pretty good). Would you like the matchmaking system to take into account his 54% win rate, and place him with 1200 Elo players than have a 54% win rate? Or would you like it to take into account his 2.5k+ Elo, and place him with other 2.5k+ Elo players, regardless of their win rate?
And remember - there are a massive amount of players out there. Having one player be 1:7 doesn't necessarily mean that they lost 7 games and won 1 game against the exact same 5 people. You could have 5 0:8 players and 40 1:0 players, very easily. On top of that, I guarantee you there are players with 7:1 win ratios.

There's a guy with an 88% win ratio, for your viewing pleasure.
