Noch ein bisschen zum ELO System von den DEVs

As mentioned, those match scores you see are not your ELO. The ELO is hidden at the moment; no-one sees it except specific devs for debugging, and the CSR team for when they need to investigate user reported matchmaking issues.

The specifics of how ELO will be implemented are sparse, but not completely missing. Paul posted a huge explanation in this thread: http://mwomercs.com/...79-matchmaking/

An important and often overlooked detail from that post is this:

Quote
A player’s rating will only go down if they are beaten by a player who has a lower rating than theirs. In this case, if the 1350 player lost, their score would not change since the Match Maker was correct in its prediction.


So if you are thrown into an unbalanced match with equally skilled opponents (6v8 for example), you should be ranked lower overall and thus, not take a hit in ELO when you lose.

The combat score which has been talked about elsewhere is an entirely separate concept from your ELO. The combat score is kind of like a 'match score' for a single game to try and give you an idea of how well you did. We're not currently persisting the match scores, and I suspect it will get tweaked quite a bit over the next few patches

So here's a question - if you're a competitive player with a high Elo rating is there a way for you to easily get into less competitive matches?


Not officially. If you're a very strong player who consistently plays well enough to generate a pretty high ELO, then one of the goals of the system is actually to protect the less skilled players from you.

That being said, there are edge cases where we're forced into situations where this might be the case. The system gets less restrictive about matching ELO values the longer you're stuck waiting for a game to fill up, so this is one case where you might get matched against lower ranked players. Also, if you group together with a bunch of lower ranked players the system needs to make some compromises here too. The ELO values are all hidden to you though, so it would be troublesome to pull this off in practice.

Logically, I would expect the matchmaking to seek to prioritise matching those with similar Elo ratings then if no equal Elo rated teams are available, match the closest available within a certain fixed band of +/- x%.

If again, no teams are available, the matchmaker would start factoring things like how long you've spent waiting for a match and expand the band by a further =+/- y%.


Yup, this is definitely the intended behaviour for the new system.

Elo ratings can be inferred from the opponents you are matched up against and comparing notes with other high rated players who will by default be a minority. Even now, there are known players who are acknowledged to be superior pilots so if you get matched with them frequently, you pretty much know you're at the upper end of the scale.


True, if you're determined enough then it's possible for someone to reconstruct, at least roughly, what relative rankings you might have based on how everyone gets matched up. There is a fair amount of other state involved in matching that you would need to correct for, mech tonnage, matchmaking wait times, game mode selections, player groups, etc.. All of this will make data mining your ELO harder. We didn't do any of this to purposefully try and obfuscate your rankings though, it's all done to try and make the matches more balanced and interesting.

Mal abwarten ^^.Hört sich an sich aber OK an .

Match Making Update

I wanted to just help clarify some points about the new match making system as there seems to be some confusion on these points:

Is the match maker taking weight class into account?

Yes the version currently live on production does take weight class into account. The way the match maker works it tries to group players within certain thresholds and grows those thresholds over time to ensure a match is made within currently a 2 minute time period.

These curves will likely see some tuning for both skill and weight as we monitor the data coming in and work to ensure more and more matches are created within good thresholds. This tuning will happen over the course of upcoming patches.

I'm still getting matches that seem unbalanced.

It will take time for the ratings to stabilize please bear in mind that this will likely happen over weeks not days. Also it's important to clarify that the system is only using your match history since we announced that we enabled it for pre-seeding. If you've been with us since closed beta your skill rating is essentially a few weeks old and only based on what you've done in that time. This is the only way to be fair to everyone.

Also currently after 2 minutes you may get an unbalanced match as the match maker increases the thresholds dramatically to ensure you get a match this is as designed to ensure that you don't wait longer than 2 minutes to find a match.

How does the match maker compose a teams Elo rating, is it average rating or closest to a target?

It's closest to a target value, so the match maker starts trying to make a match for an Elo of say 1300 and will pull in players to those teams closest to those values; however, as mentioned earlier within growing thresholds and those curves will be tuned. Currently it may be a bit 'sloppy' about how it's filling those buckets but over time it will be tuned to be much more precise.

We need to do this carefully over time as generally the cost of precision is time to find a match we want to slowly find a very nice balance between time to find a match and the number of matches that are correctly composed.

Can we expect match making to be tuned?

Yes as just stated we will monitor and tune over time to ensure it is working optimally and as everyone plays more games things will naturally settle out over time.

If your getting consistently hard or easy matches please bear with it while the system adjusts and know that we are monitoring and planning adjustments to ensure everyone gets fair matches.
