Rating System Changes
Personal Ratings will now always trend toward Team Ratings, which should eliminate the odd behavior players noticed of seeing their PR change in ways that seemed blizzard. It also eliminates the possibility that you can play every game with your team, yet be ineligible to get items when the team qualifies for them (or ineligible to receive full points).
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 ).
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. This means that most players over 1500 will experience some easier than expected rating gain as their team adjusts upward to the new scale.
Players with less than 1500 rating will still get the same number of points as players at 1500.
It is now easier to get higher ratings
It is easier to get higher ratings due to the scale adjustment. However, I'd still expect a very small percentage of the population to get the arena master achievement; by no means would I call it trivialized.
New Arena Matchmaking System - Additional Information

Team / Personal / Matchmaking Rating
Because of the way the new system works, there has been some question as to the purpose of each of the different ratings, so here goes:
Team rating: Team rating is the primary measure of a team's skill during the course of its existence. Titles and arena points are based on team rating.
Personal rating: Personal rating only exists to ensure that a player has participated enough on a team to deserve the benefits of being on that team. When personal rating gets close enough to team rating, we judge it is likely the player deserves the benefits of the team.
Matchmaking rating: This rating exists to ensure quality match-making despite players changing teams. In addition, the theoretical mathematical foundations of the new matchmaking system allows this rating to adapt much faster than team rating and personal rating, making the entire system more correct. In our measurements to date, this rating has been quite precise in predicting the outcomes of future matches.
Personal rating currently converges towards the matchmaking rating instead of the team rating, which we realize can cause lot of confusion and frustration. We will be making an adjustment in the near future that will cause the personal rating to converge towards the team rating instead of the matchmaking rating, which should alleviate much of the current concerns.
Same team, different Matchmaking Rating
Partners on the same team can have diverging team ratings if their matchmaking ratings are different. As mentioned above, we will be adjusting it so that personal rating will no longer diverge from team rating and will instead always converge towards it.
Team / Personal rating convergence
Team rating currently converges towards the average of the matchmaking ratings on the team. Personal rating currently converges towards each individual's matchmaking rating. As such, the team rating currently ends up in the middle of the personal ratings of each member of the team, usually around the average personal rating of the team. As mentioned above, we will be adjusting this to keep personal ratings in line with team ratings.
Past Win/Loss and new ratings
We included history from before the implementation of the new system in determining the matchmaking rating. If you or your partner played with another player before the new system, data from those games would also be included in your current matchmaking rating.
