Can we fix this mastery system?
I don't enjoy doing extremely well on a champion I love only to lose get 200 points while someone on the enemy team does horrible and gets like 600+ just because they won.
That's not how champion mastery should work, it should be overall performance not rather you win or lose. Sorry but I should be getting more mastery points for going 20+ kills, High cs and structures destroyed. As opposed to an enemy who went 7/19 low cs and basically was a bot the entire game.
This system is a great thing to have, you just did a bad job implementing it.
