The Importance of MMR in DOTA 2
Matchmaking Rating, or MMR, is a component of Dota 2 that every player should be aware of. It is not only something to know about for the average player looking to understand the game, but something that professional teams use fairly often in scoping out the talent of any particular player. This time, we will discuss the components of MMR, and why it is important.
What is MMR?
MMR is the value that makes the determination of the skill level of any given player — something that is then used for matching making. A player’s MMR can be increased by winning. On the other hand, it can be decreased by losing.
There are many prestigious factors when it comes to the idea of MMR. The Ranked Matchmaking system allows players to be able to earn seasonal ranking medals based on their MMR, allow some of the most skilled and highest rated players to be listed on the world Leaderboards, and the very best envelope pushers to be able to considered for records that some Dota 2 fans meticulously track.
How it works
For the most part, players of a similar MMR will be matched against each other. MMR values are also adjusted — something dependent on the role that the player selects, as well as the player’s past performances with that particular role.
MMR for ranked matches are something that require around ten games for it to be calibrated, with bot games and training matches not using any MMR. It has been a system put in place that Valve has had a multitude of updates for in the past. And it, of course, is not just as simple as that. There are other factors to take into account, though.
One thing to remember regarding MMR is that it is the primary, but not the only factor that is used for the game’s matchmaking. The system that Valve has also uses things like Experience (number of games played), Gold Difference (in game), as well as various other hidden factors.
Another thing is that this system doesn’t examine things like individual streaks or try to end them in any way. Things like win rate and win count are unrelated to MMR, and are not considered a meaningful measure of skill.
It also must be mentioned that the system does not try to attempt to directly achieve any specific win rate for a player. It does attempt, however, to ensure that every team has a coin-flip chance of winning by matching players of a similar skill level against each other. Taking this into account, that obviously means that over time, every player will settle somewhere around the fifty percent mark. Everyone except the greatest of players.
Something special about EG is that it has three players that have among the highest MMR in the game. Andreas Franck “Cr1t-” Nielsen, Artour “Arteezy” Babaev, and Abed Azel L. Yusop all have among some of the highest MMR that has ever been achieved in the game. It’s a testament to EG’s value for talent, and is one of the reasons that the team is so strong.
