Considering the source of this statement is an engineer who works on the matchmaking, that should permanently put the issue to rest.
But as anyone who reads the forums knows, nothing will happen and the same thread will pop up every 3 days just like surrender threads.
People will complain about this “forced 50%” as long as the game will exist even when multiple developers say it isn’t true.
If shown examples like Fan who keep accumulating win after win without being “forced” to lose, they suddenly have nothing to say.
Or player profiles far, far below 50% especially in Bronze.
