There has been some confusion regarding the changes to Arena Team and Personal rating calculations in patch 2.4.2 for those players with 100% participation on their team so we’d like to clarify how the system works now.
The adjustment to a team’s personal rating can vary based on the average personal rating of the other team while team ratings will always adjust based directly on the team rating of the other team. If the average personal rating of the players queuing for a game is more than 150 points below the team’s rating, the team will be queued against an opponent matching or similar to the average personal rating. Adjustments to your personal rating are based on the ratings by which the opposing team was queued.
If the opposing team was queued based on their team rating, your personal rating will be adjusted based on their team rating.
If the opposing team was queued based on their average personal rating, your personal rating will be adjusted based on their average personal rating.
Team A has a rating of 1550. Team B has a rating of 1750.
Team A has an average personal rating of 1520 for the members participating in the match. Team B has an average personal rating of 1490 for the members participating in the match.
Team A wins. Team A’s team rating is adjusted based off of a win over Team B’s team rating of 1750.
All members of Team A have their personal ratings adjusted based off of a win over Team B’s average personal rating of 1490 but it will be a smaller gain when compared to the rating their team got.
This change promotes having teams compete against players who’s ratings statistically match up best against them. In turn this will help provide the most competitive environment possible in the Arena.
