At the top of the post-game recap are a trio of radio buttons asking me to rate the match I just played. Does this rating exist only so Blizzard can run analytics at some future point, or does it have any effect on the matchmaking system (for example, encouraging a team shuffle or causing the servers to find a new game)?
New “Rate This Match” and “Rate This Player” options have been added to the end-of-round flow
Rate This Match: These ratings are designed to provide the Overwatch development team with feedback about how much you enjoyed a match. This data will be used over time to improve matchmaking and the game in general.
Rate This Player: Positive and negative ratings can have an effect on how likely players are to be matched with one another in future games.
