Dota 2 has reworked its Ranked matchmaking system, swapping the old stacking matchmaking rating value (MMR) for a range of Seasonal Rank Medals. With it, the game's inaugural six-month Ranked Season has also kicked off.
As detailed in this blog post, the new system represents players' "highest performance level for the current season"—meaning medals reflect their highest rank, despite the tier they play in. "A Seasonal Rank Medal never decreases in rank once you’ve achieved it. Initial calibration games will be seeded roughly based on your previous skill," reads the post.
Across seven levels—Herald, Guardian, Crusader, Archon, Legend, Ancient, and Divine—progression is hinged on a five-star system, which looks something like this:
The post adds: "Your performance in both Party and Solo games is considered when evaluating your skill and determining when your Medal gets upgraded, with Solo games having a bigger impact. In order for players to achieve either the Ancient or Divine Medals, only Solo-game performance is considered.
"This update also expands the Leaderboard system to include many more players. Players with 5 stars on the Divine Rank Medal (the highest rank) will now have a leaderboard number listed with the medal that broadcasts their position amongst other players. This leaderboard position will always be displayed alongside the Medal, and will be visible to all players in the game and on your profile."
