Regular players will be well aware that the matchmaking rank (MMR) calculation used by the game leaves quite a bit to be desired, particularly as your skills increase. Equally, the current system enables new players to accelerate through the MMR curve very quickly where they will often face the very best players in the game a long time before they’re realistically ready to do so.
First things first, pursuing a “high” MMR should not in itself be an aspiration. It is not a measurement of how awesome a player you are, it is simply a means for players to get a balanced game when they play, something which at present it doesn’t always do.
We know this current system is poor, and a proper replacement is being worked on, however we wanted to make a minor improvement quickly to reduce the speed at which players increase MMR in order for newcomers to improve at a more plausible pace, while giving veteran players stronger competition to test their mettle.
With this goal in mind we are making a small adjustment to the MMR calculation today.
The graph below shows how the old MMR changed with games played (in grey) and how the altered calculation (orange) will make a difference.
The old version scaled up massively with each game meaning you could hit 5000+ very quickly with few games. This is bad for everyone – players without a full understanding of the game got pushed through the tiers very quickly and would end up in high tier games that they were not ready for. In addition players also left the safety of the lower bracket way too quickly.
In the new calculation, the scale-up is more gentle and movement through the brackets is slower and takes more games. This means new players stay in the lower bracket longer (and are more likely to get matchmade to lower bracket players) and players take longer to move through the shared middle bracket.
The effect of this change will be different for individual players depending on how much they’ve played: players with between 8 and 69 games recorded will likely see their MMR drop, possibly quite significantly. Those who are between 69 and 120 games played might see a slight increase while those with over 120 will not see a difference.
Again, this is not the full solution to MMR it is intended to make an improvement to the game as it is now, a better, more permanent solution will arrive in a future update.
