For those who don't like the ranking system

I was thinking about all the people who don’t like the ranking system, and I and the idea of something that would give you a rating from 1-10 on how you preformed in matchmaking the previous week. It would simply take your kill/death ratio, wins/losses, simple stuff like that, and people could get a good idea of how good you are instead of guessing based on how long you play. Just an idea.
