Valve Compressed Dota 2’s MMR Scale and Exposed a Bigger Problem

The Number That Stopped Meaning Anything

Alan “Satanic” Gallyamov of PARIVISION reached 18,000 MMR earlier this year. Nobody particularly cared. That tells you more about the state of Dota 2’s ranked system than any patch note could.

In 2023, the Immortal rank held the top 1% of the player base, according to Stratz’s data. By 2026 that figure had reached 4.4% — nearly four times as many players in the same bracket. The distance between Satanic at 18,000 and a freshly promoted Immortal at around 6,000 was over 12,000 MMR. For comparison: the entire range from Herald, the lowest rank, up to Immortal is 5,000.

A number that takes five digits to write stopped functioning as a measurement a while ago.

What Valve Did

The Summer Scrub update compressed every Immortal player’s MMR into a 1 to 9,500 range. Satanic dropped from 18,000 to 9,462. Everyone moved proportionally. Relative leaderboard positions stayed unchanged, if you ranked #2,500 before the update, you still rank #2,500. The scale changed; the order didn’t.

Immortal Draft remains gated at 8,500 MMR, which now means the eligible pool is genuinely small. Before the compression, most of the Immortal bracket cleared that threshold. After it, SEA reportedly had fewer than 20 players above 8,500. Artour “Arteezy” Babaev said publicly he was glad to get into high-level lobbies again without the friction that had built up at the very top of the ladder. That’s an odd thing for the world’s best player to have to say about the mode designed for his bracket.

What The Compression Doesn’t Fix

Double Down tokens, which let players win double MMR from a single match, are the most commonly cited cause of the inflation. Valve introduced them. Valve has now had to correct for what they produced. The tokens are still in the game.

The Immortal Draft dysfunction isn’t resolved either. Win-trading and a non-functional Avoid Player feature in that mode had made it uncomfortable enough that several players publicly welcomed the compression because it meant fewer mandatory appearances there. The patch addressed the number on the screen without touching what made the experience bad.

What Actually Changes

The gap between Satanic and a strong amateur player is now roughly 3,000 MMR instead of 10,000. Psychologically, that matters, not because the skill gap changed, but because the number no longer reads as a closed argument.

There’s also a more concrete downstream effect. Players who were previously sitting at 6,000 to 7,000 MMR now sit just above the Immortal floor. A larger group standing close to the demotion threshold means active fighting to stay in the bracket, which creates pressure the old inflated scale had slowly drained away. Whether that holds depends on what happens to Double Down tokens.

Valve ran a clean operation on the symptom. The cause is still there.
