Mastery Points are heavily lopsided towards win/lose
I played a game as Shyvana jungle. Lost sure but the system still gave me an A. Although with that A i receive only 200 or so points. I had B+ with Tristana ADC on a win and got 1000+ points. What gives? I thought the points would be proportional to the rating. Getting an A but getting almost nothing feels like a backhanded compliment...
