How many roles are there in Dota 2 and how do they differ?

There are five roles by position 1-5: carry (pos. 1, safe lane and farm), mid (pos. 2, game tempo), offlaner (pos. 3, tank and initiator on the hard lane), soft support (pos. 4, roamer and ganker), and hard support (pos. 5, wards, vision, and saving cores). Cores deal the damage, supports provide vision, control, and protection.

Is there a separate rating for core and support?

No. Valve removed the separate core and support ratings long ago — you now have a single MMR. Whatever role you play, points go into one shared rating. So you can switch position at any time without losing accumulated points or calibrating a role separately.

What is a High Demand role?

High Demand is a role the queue is short on right now, and Dota flags two positions this way. Picking one finds a game faster and saves your Role Queue Games: since July 1, 2026 a solo player only needs to select at least one of them for a match not to spend one — both were required before. The scarce roles are usually support and offlane, because most players want the farming core roles.

How do you change your main role without losing MMR?

Just pick the new position in the ranked queue — there is no separate role calibration, and rating is not reset when you switch. It is better to change gradually: first learn the heroes of the new position in normal games or Turbo, study the timings and item builds, and only then play it in ranked. That keeps the rating dip during adaptation to a minimum.

Changing Roles in Dota 2 — Switch Without Losing MMR

Changing Roles: switch position without losing rating

Tired of farming as a carry and want to try mid? Or, the other way round, worn out by core pressure and drawn to relaxed support? Good news: in modern Dota 2 the rating is shared, and you can change your main role without calibration or losing MMR. Let's break down all five positions, how role queue works, what the High Demand bonus is, and how to move to a new position as painlessly as possible.

Five roles in Dota 2

A team of five players splits into five positions. Each owns its own job, and the result depends on how they mesh:

Pos. 1-3 — core. Carry, mid, and offlaner: the main damage and initiation.
Pos. 4-5 — support. Soft and hard support: vision, control, saving the core.
The link-up. Cores farm and deal damage, supports create the conditions for it.

The one-line takeaway

A role is not a hero — it's a zone of responsibility and a priority on resources. The lower the position number, the more gold and XP the team hands that player.

How role queue works

In the ranked queue you choose which positions you're willing to play:

Pick positions. Tick one or several roles you're happy to take.
High Demand. A scarce role is flagged separately: its queue is faster, and since July 1, 2026 a solo player only needs one such role for a match not to spend a Role Queue Game — both were required before.
Single MMR. Points for wins go into one rating regardless of the chosen position.
More roles, faster. The wider your position choice, the quicker a game is found.

Understanding each position's job is the foundation; if you haven't sorted that out yet, start with the guide on roles and positions.

Core roles: 1, 2, 3

Core positions get farm priority and carry the team's damage - the core is the most common path toward Immortal, where steady farm and closing out games matter:

Carry (pos. 1). Farms the safe lane, stacks items, and carries the late game.
Mid (pos. 2). Controls tempo, hunts runes and power spikes for ganks.
Offlaner (pos. 3). Tank and initiator on the hard lane, creates space.
Cost of mistakes. It's easier to feed on a core, so farm and positioning matter.

If you're moving to a core, sharpen your farming and last hits: resources are exactly what separates a strong core from a weak one.

Support roles: 4 and 5

Support plays on fewer resources but decides just as much, and you can climb MMR on it no slower than on a core:

Soft support (pos. 4). Roamer and ganker: pressures lanes, places vision, initiates.
Hard support (pos. 5). Wards, protects the carry in lane, saves the core in fights.
Less farm. Supports live on team auras and cheap but vital items.

Nuance

Support and offlane are often the High Demand roles: they get picked less than the farming roles. If you want fast queues and bonuses — learn support.

How to change your main role

Moving to a new position goes smoothly if you act in steps - your rating isn't split or reset, not even at seasonal recalibration:

Practice first. Learn the new role's heroes in Turbo or normal games.
Study the timings. Item builds, power spikes, and the new position's responsibilities.
Then ranked. Only once comfortable, play the new role in ranked.
Shared rating. Points aren't split by role — switching position doesn't reset MMR.

A new role goes faster with support

Switching position dips your rating temporarily while you adapt. If you'd rather not spend points on experiments — top‑1000 Europe boosters will raise the MMR on your main role while you calmly learn the new one. Not sure about the format — message us in chat.
