Thanks for this - a great start! I love to see this kind of non-economic changes that are designed to improve the gameplay experience for players-new and old alike! The current rating reset has been a real sore point for me.
While I appreciate it from my own perspective as a player, I do worry a bit that it will add more rating inflation from low level accounts that will climb together to champion leagues after a few seasons. Perhaps a later step might be to have # of games played in a season factor into the reset?
