Role MMR: one rating, five roles
There's a lot of confusion around role MMR: half the guides still describe separate core and support medals that haven't existed for years. In reality Dota 2 has one shared rating, and roles affect matchmaking, not a separate score. Let's break down how the role queue works today, what the New Frontiers patch changed and why it matters not to confuse the current system with the old one.
What role MMR is
Role MMR is not a separate rating for each position but a single MMR that works together with the role queue. You pick which roles you're willing to play, the system builds the match and assigns positions, but your rating and medal are shared across all roles. Internally the client tracks your relative strength per position so matches are fairer, but that never surfaces as a separate number.
Dota 2 has one MMR and one medal. The role affects who you're matched with and against, not a separate score — separate core/support ratings no longer exist.
How one rating works
The logic is easiest to grasp step by step:
- One MMR per profile. You have a single number and one medal; wins and losses move exactly that, whatever position you play.
- Per-role adjustments. The system separately holds your relative strength at each position so a beginner support isn't thrown in with cores of the same number.
- The Glicko algorithm. Rating is computed via Glicko: it accounts not only for the result but for confidence in your MMR, so early on the number swings harder.
- Matched on the whole. You're put into a match by overall MMR and role adjustments together — that's how teams end up balanced across the lanes.
If you want to understand the scoring math itself, read the guide on how MMR is calculated.
The role queue
Queuing by role solves an old pain — the fight over positions at the start of a game:
- Five positions. Core roles (1-2-3) and support roles (4-5) — before searching, you mark what you're willing to play.
- You can pick several. The more roles you mark, the faster a game is found; a narrow choice means a longer queue but your comfort position.
- Distribution without arguments. The system pre-assigns roles in the team, so the in-chat fights over mid almost disappear.
- Flexibility is rewarded. A willingness to play support shortens the wait and helps you grind games in the direction you want.
Which position suits you and what each role is responsible for is covered in detail in the guide on roles and positions.
What it used to be
The confusion comes from the system's history. Before 2019 there were separate solo and party ratings. After The International 2019 they were merged, but separate Core MMR and Support MMR were introduced — you could be Divine on core and Legend on support, with different medals. This is exactly the scheme many old articles still describe.
The New Frontiers patch (7.33) removed separate core/support medals and folded everything into one MMR with per-role adjustments. If a guide talks about a "separate rating for support," it's describing the outdated system.
So when reading any MMR material, check the date first: anything about separate medals per role belongs to the pre–New Frontiers era.
Common mistakes
These misconceptions get in the way of understanding your progress:
- Looking for a separate support MMR. There isn't one — the rating is shared, and you can't grind support to bypass the core medal.
- Trusting undated old guides. Descriptions of core/support medals are only valid before the New Frontiers patch.
- Marking one role and expecting a fast search. A narrow choice lengthens the queue; flexibility saves time.
- Thinking support gives less MMR. The amount of change doesn't depend on the role — it's the same.
FAQ
Does Dota 2 have separate MMR for core and support?
No. The New Frontiers update (patch 7.33) removed the core/support split: there is now one shared MMR and one medal regardless of role. Separate core and support medals are a thing of the past — many old guides still incorrectly describe them.
What is the role queue?
It's the selection of preferred roles before searching for a game. You mark which positions you're willing to play, and the system builds a match so the team's roles are distributed without conflict. It doesn't split into a separate rating — your MMR stays shared.
What algorithm calculates the rating?
With New Frontiers, Dota switched from a modified Elo to the Glicko system. It accounts not only for the result but also for the confidence in your rating, so at the start and after a long break your MMR moves faster, while a stable player's moves more smoothly.
Does the role affect how much MMR you gain per win?
The role itself doesn't change the amount: you gain and lose rating equally regardless of position. The role affects opponent matching and team composition, not the price of a specific game.
One rating — one path up
Since the MMR is shared, it's easier to climb on purpose: on a comfortable role and without pointless experiments. Want to speed up the climb — a boost takes the hard games off your shoulders while you lock in the medal on your own account. Not sure which format fits — message us in chat.
