Second ranked season: changes and new MMR measurement method

Second ranked season: changes and new MMR measurement method

Valve announced the new Dota 2 ranked season, explaining in detail all the changes, how your new medal will be calculated, and what influences the rank.

The second Dota 2 ranked season will start on June 6-7th, depending on your time zone.

  • The old season’s medal will be displayed in your profile.

  • You will have to go through the usual ten calibration games.

  • The new medal will be determined based on your performance and on your old rank.

  • Once you reach a medal, you can’t lose it for all the current season.

How your performance and MMR are calculated

Jeff Hill, software Developer at Valve, made clear how performance is measured.

I’ve done work on the re-calibration code for this season; I can answer that. For the seasonal re-calibration games, it only uses wins or losses, the relative team rank balance (match fairness) and the estimated uncertainty on your rank.

You will not get additional calibration credit for your performance in the game beyond simply winning the game. For example; hero damage, kills, assists, wards placed, creep score, gpm, hero choice - those kinds of things do not inform the re-calibration system today.
— Jeff Hill - Valve software developer

This is great news! In the past years, many players exploited the calibration games buying multiple wards, or inflicting as much damage as possible to enemies spamming abilities such as Zeus’ ultimate - all in the hope for a better rank. Now, only victories matter.

Valve also added a progress bar in the profile to show your advancement towards the next star or rank, which is visible only to you. The number of stars also diminished as they now go from 1 to 5, instead of 0 to 5.

There is also a new tier to celebrate the best players in the world that reached the regional leaderboards: Immortal. The immortal rank doesn’t have stars, but indicates your position on the leaderboard.
