It's no secret that players in Dota 2 are setting new MMR records almost every year. Alan Gallyamov, known in the scene as 'Satanic,' recently achieved something few thought possible—reaching the 18,000 MMR milestone. However, despite the apparent significance of this feat, it didn't spark the kind of excitement or celebration that similar milestones once did. The reason? MMR records, which used to be rare and impressive, have become routine, and the system itself has become so inflated that hitting such high numbers doesn't feel the same. Valve, the developers behind Dota 2, have now taken steps to address the growing problem, introducing changes in a recent update aimed at restoring balance and exclusivity to the MMR system.
The MMR inflation problem
The MMR system, which is used to measure player skill levels in Dota 2, has come under fire for being overly inflated. Just a few years ago, the Immortal rank was reserved for the top 1% of players worldwide. By 2026, that number had grown to 4.4%, meaning that roughly four times as many players were in the Immortal bracket compared to 2023. For many, this dilution of the rank has made it feel less unique and prestigious. What was once a symbol of being among the best in the world now seems to be just another common designation, with players reaching the rank with greater frequency but without the same level of recognition.
One major factor contributing to this inflation is the use of Double Down tokens, which allowed players to earn double the MMR points per win. This system, while encouraging competitive play, unintentionally led to rapid MMR increases. Additionally, there's the undeniable fact that the skill level of players in the game has improved. As more people train harder and spend more time in the game, the MMR ceiling naturally rises. However, this growth in player skill was not matched by the system's ability to maintain its balance. As a result, the gap between average Immortal players and the very top performers widened dramatically. For example, while a fresh Immortal player might have a MMR of around 6,900, the top players were reaching well over 16,000. The contrast was stark, and it made the rankings feel less meaningful.
Valve's solution
Recognizing the issue, Valve implemented a significant change to the MMR system in the Summer Scrub update. The core idea was to scale back the numbers without completely resetting the leaderboard. In the update, all Immortal players had their MMR adjusted to a new scale, where the highest MMR was reduced from 18,000 to 9,462. Now, the MMR for all players in the Immortal bracket ranges between 1 and 9,500. This move brought the rankings down to a more manageable scale while preserving the relative positions of players. For example, if a player was ranked #2,500 before the update, they remained in the same position, just with a significantly smaller MMR number attached to their profile.
Valve's changes were not a full MMR reset or a complete overhaul of the system. Instead, they focused on compressing the MMR range to make it more reflective of the actual skill distribution among players. This also meant that the most elite players, like Satanic, were no longer in the five-digit MMR range. These adjustments were designed to bring the rankings back to a more balanced state, where the exclusivity of the Immortal rank could be preserved once again.
What this means for players
The MMR deflation has had a noticeable effect on how players engage with the game. One of the biggest changes is to the Immortal Draft mode, a competitive format where players pick heroes before the match. Previously, this mode suffered from issues like unfair hero trading and broken avoid player functionality, which made it difficult to maintain fair matches. By scaling down the MMR of all players, Valve has narrowed the pool of players eligible for Immortal Draft, meaning that the majority of participants in these lobbies are now high-level players and professionals. This should lead to more balanced and enjoyable games for those who compete in this mode.
Top player Artour 'Arteezy' Babaev voiced his approval of the changes. He noted that the new MMR system has allowed him to return to high-skilled lobbies, where he can play with other top-tier players without being grouped with lower-level opponents. Arteezy specifically praised the change for making it easier to enjoy competitive play in a more balanced environment. Another important effect of the update is that more players are now within striking distance of the Immortal rank's cutoff at 8,500 MMR. This means that some players who were just barely over the threshold may now be at risk of losing their rank if their performance dips. This creates a new level of competition and incentive for players to maintain their rankings, which could lead to a more dynamic and engaging ranked scene.
While the MMR deflation has its immediate effects, the long-term impact remains to be seen. For now, the changes appear to be a step in the right direction, helping to restore balance and exclusivity to the rankings system. Valve's approach shows that they are actively listening to the community and working to ensure that the MMR system remains a meaningful indicator of player skill.
