There is a guy who only plays ashe.

He reached 10.000.000 mastery points, which is cool.

It's not like he is super good on Ashe... i don't know what he is doing all day, but i've expect him to be a bit better, with 10.000.000 points, but that just shows that you should not give too much on these scores.

Here is his mastery lookup

2nd to get 10.000.000 points is this guy who plays Heimerdinger with mouse only btw.
