League of Legends: Wild Rift Dev Tracker

We are definitely talking about ways to consider match fairness and contribution in the VP gain outcome. The goal would be to make the update at the end of the match feel more fair, while at the same time making sure the ranks were still accurate.

I can tell you that, looking at your own match history over the last 120 ranked games, the balance of rank and MMR between you and your opponents has been really even, so you've had a pretty fair schedule as it were.

If you are getting -15/+10 then that does mean your Rank is above your MMR right now. Looking at your history, your MMR is on a bit of low swing (which is normal, everyone's oscillates up and down a bit), but it tends to sit around the Diamond IV area on average.

The range of possibilities for all Diamond is everything from -15 to +15.

The way to tell where your rank is relative to your MMR anywhere Diamond+ is:

• If gains and losses are similar, your Rank is at or very near your MMR.
• If you gain more than you lose, your Rank is below your MMR.
• If you lose more than you gain, your Rank is above your MMR

So if your MMR is in the D4 range, and you are also D4, then you would see your gains be similar to your losses. Around +/- 12 or 13.

Keep in mind it's not just your tier, but your exact VP. So your MMR could map to Diamond II 50. So when you are below 50 you will net positive, and when you pass 50 it will swap the other way. Like, +13/-12, then to +12/-13. So change can happen within a rank.

oh no

To your first point, that is not what we see in the data. That happens sometimes, but it is by far not the rule. If two teams have the same MMR, it doesn't matter what their ranks are consistently in millions of millions of data points. So what you are seeing is likely confirmation bias.

To your second point, we are going to have to disagree. Data shows clearly that heavily unfair matches definitely lead to players leaving the game, and this is very consistent across millions and millions of matches and players. So, again, this is likely your own personal bias, and is not established in the data. You may not be a player that will quit because of this, but others will.

Because of how the ranking system works in lower ranks, it is possible for players of almost any skill to eventually work their way into lower Diamond. It becomes harder and harder, but is still possible, and definitely does happen due to random luck and/or being carried.

It's also very easy in the data to identify which players are which. All we have to do is see which value better predicts whether or not they will win their next match. If MMR predicts whether you win accurately, then it is an accurate judge of your skill. If Rank is NOT predicting whether you win accurately, then Rank is NOT a good judge of your skill. So all we have to do is check which of those two more accurately predicts whether or not you will win, and we know whether or not you belong at your rank.

In addition, like I already said, the data also show that if we give players matches that are too difficult given their MMR, regardless of what their rank says, they are consistently more likely t...

Fortunately, players in a 5q will not get inflated MMR, that's one of the improvements to the system. So when they go back to solo queue, they will be matched near their MMR still.

We are actively working out improvements to the current premade situation, though I don't have anything to announce at this time.

But, yes, we are very aware of how it currently is working.

OK, I'd need more info to pull the exact match, but a Master partied with Diamonds will be considered a Diamond party.

Emerald players can match +1 (Diamond) and -1 (Plat). So if you match with an Emerald, you can also see Plats.

In addition, if you are in a duo, you can see Golds if this happens:

• high Gold duo with a high Plat will be considered a Plat team
• Emerald soloQ player can match Plat (-1) and Diamond (+1)

So you have a Gold on your team, but they are partied with a high Plat, and that party is, on average Plat.

Are you in a party? And this is Ranked?

Yeah, this is where things get tricky again. The Ranks in Diamond+ are skill-based, and in any skill-based system, players will eventually ramp up into a wall once their Rank starts to approach their actual skill. The trade-off happens in balancing the steepness of that ramp against the integrity of the Ranks themselves.

In an ideal system, players realize they are ramping into that wall and know the only way up is to play better than they have been. If they actually do play better, the system should raise their MMR, with the Rank following. So players feel the system is good because it recognizes them actually improving in skill. They then go repeat the process as far as they can. Eventually though, most players will come to a plateau that they won't pass without getting to an incorrect Rank, and ruining the integrity of the system. Once players hit that plateau, they have to decide to keep playing or not. Hopefully they just play because the game is still fun and they enj...

Yes, this is a good point and one we are actively discussing. FYI, the following info is how VP gains have always worked, long before I joined the team.

Currently VP gains are based on the distance between your current Rank (tier, subtier, and VP) and the average MMR of players that also have your same rank. This is because MMR predicts who will win far better than rank does (10-15% more absolute accuracy, which is pretty significant).

So if your MMR is the same as everyone else around your Rank, then you will earn around +/-15.

If your MMR is lower than others around your rank, that can drop to +10/-15 if other players have an MMR much higher. In Masters/GM/Challenger, this can drop to +10/-20.

If your MMR is much higher than most around your rank, you can go up to +15/-10 in Diamond, and +20/-10 in the higher Ranks.

There is also a minimum MMR bar for Diamond. Basically, we say, "We want Diamond to start at the top X% of players by MMR" Ho...

So MMR is equivalent to taking a player's win rate, and then modifying it according to how difficult their matches have been. So in most cases, win% is redundant in the presence of FFA MMR and would just slow MM down. In cases where they disagree, (e.g. 48% win% but high MMR), MMR correctly predicts the winner making the low win% is misleading. Of course if both are low, then the player plays poorly as expected, but that makes it redundant again. Likewise, players with higher win% (e.g. 52%) but low MMR tend to play much worse than their win% would have suggested, which disappoints folks in general.

I think the problem you are running into right now is tightening just how low of an MMR player you can have in your match, even when they are close in Rank. That's something we are investigating.

Hey folks, as of Patch 3.0 voice chat is back in testing in the Americas and we need your thoughts in a couple of key areas to keep moving forward with enabling voice in other regions.

1. How is the voice quality? Lag spikes, voice cutting out, unwanted sounds and so on.
   
2. Are there functionality issues? We're aware of a couple of quirks but any that actively block you from using voice?
   
3. Anything else regarding voice chat?

Oh, also, sorry, I realized a made an major edit after posting the longer message above, so re-reading it may make some things more clear.

We have found that winrate is ironically not that accurate at predicting whether players will win future matches. They do have some correlation, high-MMR players do tend to have high winrates. But we also have plenty of low-skilled players who played in, e.g., 5qs and have higher win rates than you would expect for their actual skill level.

So we use MMR instead, which is actually very accurate at predicting whether a player will win a match, and play as good as their teammates. Though, keep in mind, every player tilts within about +/-1 ranks from their actual rank during any given match. But, yeah, if MMRs are close, you will probably be happy with them.

Yeah, I totally agree that it is better to have players as close to your skill as possible on your team.

Improving this requires tightening the allowed player to player skill gap, making it more likely that each other player on your team (and in the whole match in fact) is closer to you in skill.

This is something we are actively working on. One trick here is that wait time grows exponentially with this particular gap. So it becomes not a question of, "I'm willing to wait another 10 minutes" but instead another 60-120 minutes (as I mentioned in a previous post). Especially when you need to find 10 players at the high end all close in skill.

To deal with this, the current system detects real-time availability and tries to give you the closest 10 possible players. So sometimes, it can make very tight matches. At other times, the system gives up because it knows that even after 20 minutes, the match quality will be the same. We do have some settings within thi...

These are valid concerns.

1. In the data for the last month or so, I don't see Golds ever in matches with Masters. There was a window where we were testing the matchmaking parameters overall and did allow that, but we have since closed that off. Do you know when you saw that? If you have a date and screenshot so I can pull the match, I can look. So far every example I've looked up was legitimately within the rules. The only strange matches that happened involved a trio where 2 higher-ranked players brought in a lower one, stretching the gap.
2. We are aware of how stacking is affecting both fairness and the leaderboard and are actively considering solutions. On the one hand, players in 5q are pretty happy at the moment because ("having the most fun I've ever had in WR!"), which we don't want to take away, and they only match other 5q parties. However, we also know they often have the potential to climb faster than solo queue because of higher win%. We are investiga...

If the anchor is Emerald, they can match -1 (Plat) and +1 (Diamond) so you can see Plat to Diamond in the same match.

A GM anchor can match high Emerald ( I only) to Challenger so you can see Emerald I to Challenger in the same match.

Other combinations require parties since a party's rank is the average of its members.

What rank are you?

The current allowed range is +/- 1 from the anchor player or party's rank, but there are exceptions at the top (Diamond+) because otherwise they wouldn't find matches.

So if you are Platinum, you can match both -1 (Gold) and +1 (Emerald). So if the anchor player is Platinum, you can have both Gold and Emerald players in the match.

If you are Diamond, you can match -1 (Emerald) but you can also match up to Challenger because population thins out super fast GM+, so Challengers can't play w/o Diamonds. So if a Challenger player is the anchor --- which is common because anchors are usually whoever has waited the longest, and Challengers often wait the longest because of high rank and MMR --- then you can have Diamond all the way up to Challenger players in the match. Though you can't have Challengers with Emeralds unless you have, e.g. an Emerald/Diamond/GM trio that averages to Diamond.

If your rank is in those higher levels though, e...

Yes, we actually have some more advanced AFK detection running silently right now and we are gathering cases to review manually before we start issuing penalties using the method. It's actually be on live for a while, but our first review last year showed too many false positive cases so we went back to tune it some more in the latest patch.

Yeah finding people who are running it down is something we are actively improving. We're still at the stage where we are only comfortable penalizing really, really obvious cases though. We don't want to penalize people who are trying, but just playing poorly :(
