I don’t get how came up with the idea of giving either 2% or 30% for a win/los in the ranked games.
It is extremely frustrating, to grind 10 games to receive only 20% and lose 30% by only one lost game. Especialy wenn you fight agains two Champions as a Dimond 2 and the game thinks that you should win this, so it takes 30% instead of 2%.Change the it to 2% and 10% and/or fix the matchmakingstats when you are suppost to win/lose!
Have a read over the pinned matchmaking feedback topics in the Matchmaking forums, there are some in-depth posts about the system there - how it works, why it works the way it does. If you still have questions then feel free to make a post in the latest pinned thread. Thanks
