Valve Introduce yet More Changes to Dota 2 Matchmaking System

Valve are still on the track of updating their matchmaking system for Dota 2 with the goal of improving its quality. This time they introduced the following changes:

  • For any party that includes an Immortal player, every player in that party will be considered the same rank as the highest player in that party
  • Parties consisting of five players will now be matched exclusively against other parties of five
  • Solo players can now be matched against at most one party of two, meaning that a solo player will now always face either a team consisting of five solo players or a team consisting of three solo players and one team of two
  • Improvements to Role Symmetry system, including a bigger emphasis on having supports not be the highest MMR players in a game
  • Number of stars per medal reduced from 7 to 5; due to this rebalancing most players’ medals will be adjusted upwards
  • Players’ medal will no longer remain at their high-water mark, instead if a player is more than one star away from their actual current rank their medal will be adjusted to reflect that
  • Post-game screen will now show the average and max queue times for players in the match and a summarized behaviour score. Besides that, the players on the post-game screen will now be sorted from left to right with position 1 through 5
  • Players will once again be asked to conduct post-game surveys to rate their experience in a match
  • Players with a behaviour score below 3000 are no longer able to use text or voice chat
  • The acceptable MMR spread within a party reduced from 2800 to 2000

The developers also mentioned that they made significant changes to the core matchmaking code to better look through large number of players being simultaneously in a queue and improve detection of boosters and exploiters. Going forward, matchmaking will remain one of the main focuses of the development team. In the next update they will also try to improve the new player experience.

Valve started to experiment with Dota 2 matchmaking this summer, when they introduced role-based matchmaking.
