Guild Wars 2

Hello all, I have lots of questions regarding the new system, I hope Justin or any other developer can answer them. I have been reading carefully the http://wiki.guildwars2.com/wiki/PvP_Matchmaking_Algorithm and still there are parts I dont understand.

Thank you in advance for your time invested.

1) Is MMR also changing in Unranked arena?

2) What are the DETAILED differences between Unranked and Ranked arenas? just ladders? Nothing else?

3) How does MMR change after a match? I know Deviation and Volatility are in the equation, but how are these values affecting? There must be other parameters affecting the MMR after each match.

4) If I win a game, does my personal MMR change according to the AVERAGE MMR of the enemy team? or does the equation also include the AVERAGE MMR of my own team?

For example my MMR is 2000, the average MMR of my team is 2100 and the average MMR of the enemy team is 2300.
My team wins ==> How is my personal MMR changing?
My team loses ==> How is my personal MMR changing?

Second example: my MMR is 2000, the average MMR of my team is 2100 and the average MMR of the enemy team is 1900.
My team wins ==> How is my personal MMR changing?
My team loses ==> How is my personal MMR changing?

4) Do we keep the MMR from pre-patch?

5) How is the MMR from pre-patch divided into the different MMR for the different classes?? Is my previous MMR weighted between all my played classes? Let’s say I played 70% thief, 20% warrior and 10% ranger, is my MMR accordingly weighted?

6) In Match Prediction (or Odds of Victory) why position in Ladder from both teams is not taken into consideration? Right now only MMR, Team Size and Rank is taken into consideration, why Ladder position is not? I think if one team is located higher in the ladders should have more Odds of Victory as the other one.

7) Why minimum Deviation possible (in MMR) is 30 and not 0?? If I play every day my deviation should be 0 (or 1 if 0 gives mathematical inconsistencies)

Thank you again, and sorry for the orthographic errors, English is not my mother language.

You’ll have to read both the ArenaNet posting about the new PvP, and search for developer posts in this forum…Many of these have been answered already

I already read the ANet posting about new PvP, and my questions are not being answered there.

And I also think this thread could be used as a summary thread to find the answers to all those questions that not only me, but also many other players, are asking all the time.

P.S: the search tool is really bad with such a big mess of QQ posts from unhappy players.

No everything you have asked has already been answered
One thing you are right about is how bad the search function is

http://wiki.guildwars2.com/wiki/PvP_Matchmaking_Algorithm#Pseudo-Code

The search function is awfull!

I have read the algorithm wiki and since I am no programmer I don’t understand the Pseudo Code part. I can only understand the Parameters and try to guess how they work.

But that’s why I am asking here if any developer could answer those questions I posted, cause that would help a lot of people to understand better the actual System.

And I am completely sure many of those questions have not been answered yet!

Mainly the one: How does MMR change after a match?
There is nothing in the wiki that explains that Point.

I have a question too.

leaderboards Team Arena = Ranked Arena?
Solo Arena = Unranked Arena?

I have a question too.

leaderboards Team Arena = Ranked Arena?
Solo Arena = Unranked Arena?

The leader-boards are currently still the same ones as before patch. They will be wiped once the Season starts.

Roc.6143:

I have a question too.

leaderboards Team Arena = Ranked Arena?
Solo Arena = Unranked Arena?

As you can see there are still players with big BASIC questions.

I strongly think this topic could be like a place to summarize them all.

If only a developer could answer some of them it would help a lot the community.

And as stated before, not all of my questions have already been answered in other topics, or are good clarified in the ambiguous PvP Algorithm Wiki web site.

MMR is calculated via Glicko2.

http://en.wikipedia.org/wiki/Glicko_rating_system

Assuming they are sticking close to that algorithm, there’s your formulas for rating changes. I believe the opponent MMR is the average of the opponent team, but could be they made it a bit more complicated.

Out of curiosity, why do you need to know exactly how MMR is working in this game at such a low level? Your value is not exposed to you.

Cause knowing my MMR would tell me how good or bad I am.

It should be shown in the main Statistics view together with amount of games played and so on.

Right now I play against a team I do good my fights or rotate good and my team wins. Next game I don’t play so good, I am more slow in my rotation and my team loses.

Did I win cause first enemy team was worse than mine? cause I was more inspired? Or they just had a bad game or a bad composition and I was there to take profit of it?

Did I lose cause second enemy team was better than mine? cause I was thick in that game? Or I was just paired with bad players or the wrong composition?

So I could be wining against good players and losing against bad ones or other way round….

So basically knowing my MMR, would tell me much more information about my actual skill level and how far I am from the average (above or under).

Still no developer answer….

It’s a long explanation and no one wants to write you an essay here. Really. Search using Google for GW2 matchmaking. It should give you lots of hits on Forum posts talking about it.

The MMR is a number and also a confidence value of how accurate the system thinks your MMR is, based on how many times it has seen you play,
