Several months ago, Valve introduced a significant change to the matchmaking system of Dota 2 that was not appreciated by the community. It gave precedence to “behavior score” more so than majorly taking into account the actual matchmaking rating (MMR) of players. The end result was broken matchmaking where high-skilled players would often be matched against low-skilled players based on their in-game toxic behavior towards others.
Valve clearly wanted to create a more friendly competitive environment in Dota 2. However, the experimentation did not yield favorable results and only created frustration for many.
After listening to criticism for months, the developer has finally decided to adjust the matchmaking system. A new update released for Dota 2 earlier today makes the in-game behavior score less significant over the player-rating for the general population. However, the worst offenders will still be part of the previous system and may possibly be matched against those who are not well-versed in high-level Dota 2 play.
In addition, matchmaking is now more sensitive to the number of games played on an account but will not replace the smurf-detection policy. New accounts with higher-than-usual statistics will still be matched according to skill-rating instead of the sheer number of games played.
Elsewhere, the developer has also improved the detection of exploiters, bots, account sellers, and in-game feeding. Expect more matchmaking bans to be awarded to such types of players in the coming weeks.
Valve hopes that the new changes will allow for better quality matches in the game and curb toxicity levels from Dota 2.
