Over the past several months we’ve been working on improving matchmaking. In this post we’d like to share with you where matchmaking currently stands and give you a sneak peek on an upcoming matchmaking feature.
The next major update will add a ranked matchmaking feature to the game. This mode is aimed at experienced players who want to play in a more competitive environment and know their matchmaking rating (MMR). Dota 2 matchmaking has always calculated MMR and used it to form matches; in ranked matchmaking we make that MMR visible.
Each of the two ranked MMRs has its own calibration period. Under certain circumstances, we may need to reactivate calibration, if we think the MMR is inaccurate.
