Riot,here is a reason why should you fix matchmaking(small text, no rant)
When you stop balancing ranked games based on winrates/MMR and make a system which actually places similiar ranks together, you will get happier players. Games will be more balanced. Happier players = More money(The more moneys for rito the happier feelies rito) Not saying that people don't buy skins at all or anything like that, but I'm pretty sure that some people are so tilted sometimes, that they don't even bother wasting money on RP. But if they'd be happy then they would. So just do it Riot?
