In response to customer feedback regarding the ranked games we have decided that summoners must reach level 30 in order to be able to participate in ranked play. While we understand that this will spell disappointment for some, we believe that it is important to ensure that the playing field is level before players do battle in a ladder setting. We made this decision in response to our initial data from ranked play, which has shown that players below level 30 leave up to 4.2% of games while level 30 players leave around 1.1% of games. Additionally, players below summoner level 30 trend towards win rates as low as 35.2%, whereas summoners of level 30 currently have an average win rate of 52%. We have also shown that overall player quality improves drastically as summoners level up to 30. We've attached a few graphs to help illustrate the point.
For those players whom this affects, we apologize for the inconvenience. But don't give up! Your current ranking will not be lost while you finish leveling. You're so close to the finish line! Courage!
