It's a useless system. They need a W-L ratio instead. People use second accounts to boost in the top 50, lose to a noob and you drop a lot (the noob could be someones second account), and the fact that people obsess over it instead of their record. Wouldn't it make sense to have a system where it's not easy for people to boost or have other accounts? W-L ratio will show the top 50 people who have the most wins over losses.
