Q u o t e:
Now, when I play arena and start a new team with a paladin and we play 19 games and have a13-6 ratio, our standings are as follows:
teamrating: 1620
partner personal: 1645
my personal: 1552
I have to say, I am very disappointed to see we spend the same amount of time and effort and almost seeing 100 points difference in personal ratings.
Due to there being some confusion regarding the ratings, we wanted to clarify a little:
Team Rating Team Rating is the primary measure of a team's skill during the course of the team's existence. Titles and arena points are based on the team rating.
Personal Rating The intention of this rating is only to make sure that a player has played enough games with their team to deserve the benefits of the team's standing and rating. When a player's personal rating gets close enough (within a certain range) of the team rating, it is considered likely that the player deserves the benefits of the team.
Matchmaking Rating (Hidden Rating) The purpose of this rating is to ensure quality match-ups for a team regardless of players changing teams or resetting their team rating. Additionally, the theoretical mathematical foundations built into the matchmaking system allows for this rating to adapt and change much faster than team rating and personal rating; resulting in making the system match teams more correctly.
We should note that in our measurements thus far, this rating has been quite accurate in predicting the outcomes of future matches.
--------
That being said, we feel it is important to note that currently the personal rating of a player converges towards their matchmaking (hidden) rating rather than the team rating. We realize this is a source for much confusion and frustration with the players and will be changing the way it works a little: Instead of having the personal rating of each player converge towards their matchmaking (hidden) rating, it will instead be converging towards the team rating. We believe this change will help alleviate a lot of the current concerns and frustrations players are reporting.
Something that we wanted to take a minute to clarify is the fact that
the matchmaking (hidden) rating is solely based on the history of wins/losses for your team(s). It does not factor in your gear, damage or healing done or any of the other speculations and rumours flowing about these forums. Another clarification to an issue which is causing some confusion is the fact that a team's members can (and often does) have different personal ratings from one another as well as differing from the team rating. The reason for this is the following: A team's rating currently converges towards the average of that team's matchmaking (hidden) ratings while a player’s personal rating currently converges towards his individual matchmaking (hidden) rating. As mentioned above; this converging of personal rating will be changed to move towards the team's rating for a more consistent and less confusing result.
In regards to the question as to why team members who have played every game together exclusively and not with other players are getting different individual matchmaking (hidden) ratings, the reason is the following: When calculating the matchmaking (hidden) rating, we included match history from prior to the implementation of the new matchmaking system. In other words, for players in teams who have played with other people during this current season prior to 3.0.8, the data from these games are also currently included in the calculation which determines their current matchmaking (hidden) rating.
Lastly, we also want to dispel the rumours that there is one unified matchmaking (hidden) rating for all brackets making a player’s 3v3 performance count towards his matchmaking in 2v2 teams. Simply put, there is a separate matchmaking (hidden) rating for each bracket that is pertinent solely to its respective bracket.
We hope this helps alleviate some of the confusion.
