Rating system changes last night

We made some adjustments to the rating system last night that are now in effect.

1. Personal Ratings will now always trend toward Team Ratings (instead of the internal matchmaking rating). This should eliminate the odd behavior players noticed of seeing their PR change in ways that seemed bizzare. 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).

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. This means that most players over 1500 will experience some slightly easier than expected rating gain as their team adjusts upward to the new scale.

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

Q u o t e:

-Is hidden rating wiped on character transfer?
-What determines hidden rating besides win/loss? Resilience, damage, healing?
-What is the min/max amount of points able to be lost/won now?
-Is the TR/PR cap still 3000 with these changes?

- no
- only winning/losing determines the rating
- 24
- edit: didn't read this one correctly at first, yes TR/PR do still have a hard cap at 3k, although we don't expect players to get that high regardless.

Q u o t e:

And I'm almost certain that they do.

They absolutely do not, none of the rating systems have the slightest clue or are in any way affected by what gear you have.

Q u o t e:

It apear to be easier to get high ratings atm. Won´t this change trivialize Archiviments like "Arena Master" and "Flawless Victor"? If so, do you guys plan to rise the cap?

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.

Q u o t e:

How can the ratings not get that high if numerous teams get to 2700+? Are there diminishing returns on the amount of rating you can gain off another team despite team ratings being similarly high?

It certainly is possible to get that high legitimately, although it would be unusual. There's about a 2% chance of seeing a 3000 rated team in a population size of 20,000 teams... about a 5% chance of seeing one in a population of 50,000 teams. So, with the number of battlegroups in existence it wouldn't be outside the realm of possibility to see a 3k team. Grats to them. =]
