Rework the Champion Mastery system.

The champion mastery system is ridiculous. While I do like the idea of leveling up a certain champion and having a banner to show your skill with that champion the grinding part of getting that mastery is ridiculous. You should get Champion Points based off of how well you did in a game not if you won the game or not. I have over 20 champions at level 5 mastery and when I get level 5 mastery it doesn't feel worth it. Having level 5 mastery doesn't say "Hey i'm good with this champion" it says "Hey I won X amount of games with this champion". The only time I think this person is good with their champion is when they have level 7 mastery. Because then I know that they are good with that champion because they had to play good to get that mastery. The grading system is fine but only getting an extra 50 champion points based on how well you did in the match is ridiculous. It is so infuriating when you do extremely well in a game and get an S but you lost the game so you get no Champion Points. Also having to use Blue Essence to get level 6 and 7 mastery is stupid. You already know why it's stupid so I won't go into it.
