Balance aside, because that's a whole different post, the fact of rating loss and gain discrepancy being so egregious is directly discouraging players at best, and enforcing a gambler's fallacy at worse (and most common). When the scenario of a loss's absolute value being greater than or equal to the value of two wins, this means that a 66% win rate is discouraged and the only way to move up the ladder is with at LEAST a 75% win rate. These numbers are arrived by 2 wins (which can have the value of 8, in my case) do just as much good as one loss (equaling -16 in my case) does. This is 2 wins out of 3, or a 66% win rate. If you win 3 times out of four (75%), this is the ONLY way to rise up on the board.
This isn't impossible, but highly improbable. Out of the three days this season has been out, I've seen at least 20 players in the top 5 lose rating as they play more. One of my friends were #1 and TWO LOSSES brought him down 70 rating. A popular twitch streamer lost 44 points in one game, and has a less than 75% win rate in the past 9 games and has lost rating because of this. When an unrealistic standard is enforced for god knows what reason, where it seems like playing LESS games is the most beneficial for you, guess what the player base will do? Play less games. The most awful fact of this is the fact that a 50% win rate will result in you being in bronze.
How can you ban and dishonor win-traders when you are creating an environment where their existence is almost necessitated?
