What does the rest of the community think about the current MMR calculation?

I have been playing lol since S6. I never really got decent at the game until S9. I was placed in gold 4 at the beginning of the season and cruised to gold 2 fairly easy. This is otherwise known as elo hell. My stats were affected by people that flamed, inted, played champs for the first time, one tricks, etc. I could pop off and go 12-3 or something and still lose the game for other people's... lack of maturity. This made it very difficult to reach plat 4 (where I am now). I still get these teammates somehow too.

I just think that a player individually that plays well in a game (in solo/duo queue) should not 1) lose as much LP for others errors and 2) drastically affect their MMR, because that is not their true MMR. The algorithm that is currently in place is out dated and causes a lot of good players to give up playing. I have read people suggesting a flat MMR scale amongst others. What does the rest of the community think should change & what does riot plan to change?

They have the same problem as up to 7 years ago

INTers, AFKers, Smurfers - Things artificially effecting it Working off of a calculation system built for 1v1, not 5v5 - Things naturally wrong with it

That's why MMR is not built for 1v1? You run K variables independently by player. The solution to this issue is not a mystery. Cuz you can test mathematic systems with RNG values and chart the results. If you ran a single Elo adjustment with each player having equal stakes in a game then yes there's an issue. Running it for individuals takes a bit longer to collapse into a curve but it will still do so. Then its on the devs to optimize it at which point your welcome to have issues with the things Riot does.

There is a reason its the standard core of MM and Rating systems. It works. Gameplay experience is not considered when you make this kind of system.

https://www.microsoft.com/en-us/research/project/trueskill-ranking-system/ Here is a well documented MMR system if you want to take a look at them in more depth. Please stop spreading the lie that a 1v1 system is used as that's not been true for ages.

Riots biggest issues are Demotion protection creating inaccurate representations of "skill" Division 4 is a huge range to demote from so you frequently see players in it being placed 1-2 divisions lower as their match average. This throws off perception of Title = skill. Plus they change the Ranges a Rank has represented over the years. Some might argue that's to deal with inflation, personally I think they just wanted more players to get the carrot reward of Gold. You can easily compare season 1 player % of gold to modern population with a few google searches.

And duoing which is done to appeal to casual folks who wanna play with friends. Massive population % gap between silver 4 and Gold 1.

Why link something that Microsoft has done

Becuase it walks you over the steps taken to adapt Elo raiting for individuals in a team game and provides a high amount of details so you can check the logic and math.

Where as if I used riot? "We use mmr"

Or in earlier season

"We use a modified version of the Elo system. The basic gist of the Elo system is that it uses math to compare two player ratings to guess the game result"

"We modified this for team use."

The details are not provided besides a link to wiki on elo.

"basically, the concept is that you get a team elo based on whoever is on the team, and if you win, it’s assumed that everyone on the team was “better” than the guess, and gains points. There are some problems with this, but it generally works out, especially if people use pre-mades a little bit.

We also do a few little things to nudge your elo rating in the right direction when you start out so that people get where they need to get faster. We use various proprietary methods to identify players that are significantly more skilled than a typical newb, and boot their rating up a bunch behind the scenes when we notice this. Gaining levels boosts your elo rating a lot. This further helps separate level 30 summoners from low level summoners.

For more details on how the Elo system works on a theoretical level, you can read about it at: http://en.wikipedia.org/wiki/Elo_rating_system"

Just think that you climbed having negative winrate, so think if u really deserve to be in that position

S9 Elo =/= Real elo
