Riot Games explains League of Legends Ranked MMR redistribution and hints at new tier

Riot Games has outlined why it recently reshaped League of Legends’ Ranked ladder, after players reported noticeable changes to their climb across the 2026 season.

In a developer blog post published on March 2nd, Matt ‘Riot Phroxzon’ Leung-Harrison, Lead Gameplay Designer at Riot Games, said the studio adjusted how hidden matchmaking rating (MMR) maps to visible rank in an effort to tighten match quality at both ends of the ladder.

According to the post, Riot’s broader goal for Ranked is that each tier should represent a broadly similar “spread” of game knowledge and execution, using Gold as an example of baseline objective play and lane priority.

Riot said that, over time, the skill gap between the very bottom and very top of the ladder has widened significantly compared to the early days of Ranked, which launched in 2010.

At the lower end, Riot pointed to Iron having an “outsized population” — “around 14% of players globally” — including many long-time Iron or Bronze-bordering players who still have a working understanding of mechanics. Riot argued that this made it harder for genuinely new players to find fair matches while learning the game.

As a result, Riot said it adjusted the MMR-to-rank relationship to move more experienced players out of Iron and into Bronze, with the stated aim of making Iron “a home for players who are still learning the ropes.”

The post also floated the possibility that this may not go far enough, adding Riot could consider “an entirely new rank below Iron in the future.”

At the other end, Riot highlighted Diamond as the tier with the largest intra-rank variance, claiming the difference between Diamond IV and Diamond I has been comparable to the gap between Bronze IV and high Silver in recent years.

To address that, Riot said it reassigned some of the higher-end Diamond MMR range into Master, noting those players were often already being matched into Master-level games anyway.

Riot also warned that widening Master’s MMR range has had knock-on effects: it has increased the League Points (LP) requirement for Grandmaster and Challenger, despite those tiers still containing the same number of players. Riot said it is considering changes for next season.

While these changes are aimed at solo queue, Riot’s ongoing work on Ranked tends to influence the broader competitive ecosystem in two ways: player development and the stability of high-elo practice.

If Iron better separates first-time learners from long-term low-rank players, it could create a cleaner on-ramp for newcomers looking to take the game seriously — including those who eventually transition into organised play through amateur circuits, collegiate leagues, or regional development systems.

Meanwhile, the shift of top-end Diamond players into Master — and Riot’s acknowledgement of a growing gap inside “Apex tiers” — may matter most for semi-pro and aspiring pro players, where consistent, high-quality practice environments are a constant talking point. Riot explicitly noted the increasing spread between a 0 LP Master player and a 900 LP Master player, suggesting further tier expansion is on the table.
