In Season 3, we will be adjusting the way that Casual matchmaking pairs players. For the last four months, the Casual playlist has been based off of your Ranked Matchmaking Rating (MMR), as noted by this communication. In order to address this issue and provide better quality matchmaking, we will be introducing an independent Casual MMR. The Casual MMR will be based off of your performance in Casual play and is no longer tied to your Ranked MMR. Beyond the separation of Ranked and Casual MMR, we are implementing a system for new players that provides them with a base line MMR that is more on par with where a beginner should be. A lower starting point for beginners means that they will be able to increase their MMR in a pool of players with a comparable skill level. This lower MMR rating will be erased over time as they win more matches, eventually placing them where they truly belong based on their skill level. This change to Casual Matchmaking will be going live with Season 3 – Operation Blood Orchid, available on all platforms starting September 5th!
