In addition to all of the blue Arena discussions that were recently posted on the official World of Warcraft front page, some changes to the rating system are now in effect. Below is the basic list, but Kalgan posted more details in the original thread.

1. Personal Ratings will now always trend toward Team Ratings (instead of the internal matchmaking rating).

2. You will now gain or lose around 12 points when winning or losing to teams of roughly equivalent matchmaking rating to your own team (previously this number was 8).

3. The rating scale has been extended to a range of 240 to about 2800 to more accurately reflect what was possible under the old system.

4. Players with less than 1500 rating will still get the same number of points as players at 1500.
