Valve have released an experimental update for Dota 2, which introduces fundamental changes to the game’s matchmaking system – the removing of separate Solo and Party ratings, as well as the introduction of role based matchmaking with separate core and support ratings.
Now players will be able to select their roles before the start of the search: Hard Support and Soft Support fall into the support rating, while Off Lane, Safe Lane and Mid Lane affect your core rating. These ratings will be used whether you play solo or in a party.
These changes will be tested until the end of the season. Valve will decide in which direction to move forward based on users’ feedback and gathered data. In the coming year the developers also want to improve the matchmaking system by focusing on intra-team balance, player conduct, new player experience, abusive behaviors, account buying, friend and teamplay aspects, high mmr matchmaking dynamics, and other issues.
The rework of the matchmaking system is the first part of the earlier announced Summer Scrub update. The second part will be released in the near future and include bug fixes and quality of life improvements.
