Valve has announced a new Dota 2 update.
– Full parties are now permitted to match against any valid opposing team, and are no longer required to match against a full party in ranked.
– Adjusted matchmaking tuning to make finding a game as a full party faster.
– Full parties may now all chat “gg” to surrender a match after 30 minutes of game time with the same 10 second countdown and cancel UI as in pro games. This is scored as a loss.
These changes are currently experimental, and Valve will inspect the results to adjust the matchmaking system further.
