    Lets have a DISCUSSION about the MMR Ranking System in Dota2.

    Before we begin I like to apologize for my writing. Hope people focus on the discussion, and not the presentation.

    I’m making this post because I want to bring attention to this special ‘feature’ that I believe it’s seriously overlooked, but IMO is single-handily the most detrimental/sole(root)problem in Dota.
    The ‘Public Availability’ of this system is what most problems in Dota arise from.
    Everything ranging from Toxic Behaviors, Repostings,
    to human effects such as anxiety, stress, depression,
    to game social interaction and mmr class discrimination.

    If you look back prior to the MMR system being unveiled to the public, Dota2 was a different game WITH a different social culture. The problem listed above was less frequent, and people ‘Enjoyed’ playing the game.
    Dota Pre-mmr was like the friendly town social bar people would go to spend a few hours afterwork to hang with people, chat, and relax/have fun.
    All that changed and in the course of several years the psychology of the community got rewired.
    Instead it all that slowly started eroding. The pursuit of gaining a higher number became the goal. The desire to show others that they are better with their number became the focus.
    Slowly the problems stated above dramatically increased, and still increasing every year.
    People love the game, but they don’t enjoy it like they used too.
    Jumping on a Ranked Game is Stressful. It’s brings unwanted problems, but yet they try because they feel ‘forced’ to increase that Number. They feel everyone is judging them based on their MMR and if they are not high enough...then the community labels them as failures.

    Many disagree with Dendi, but he has an excellent point.
    MMR is just a number.
    Unfortunately the culture/community in Dota changed so much in the last couple of years after the introduction of the MMR system that they outcast-him, and label him(and many other)as failures.

    So what do I propose?

    I say VALVE should publicly get rid of the ranking system.
    They can keep that data to themselves, but erase it from public view.
    At the same time reintroduce a new FRIENDLY SYSTEM system that motivates, AND REWARDS people.

    This of course will have many angrily voicing their dissatisfaction/displeasure with the direction the game will take. The sad truth is because they don’t want their HIGH Status to go away. They want to be special/different from the rest.
    In time this will pass.

    So how does this new Ranking System would look like?
    How does it work, and how can it prevent the problems the current system has?
    Would it be like a traditional sport?
    Would it be none at all like in the UFC and focus on Heroes/Position played?

    I don’t know, but we can start the discussion here 😊

    * After-game MMR is same for all team players
    * It is extremely hard to increase your MMR, because player effort is not considered during MMR calculation at all

    SUGGESTION - New MMR System:

    * Fair distribution of MMR across team players (getting same MMR for bad play in the winner team not fair and vice-versa)
    * System, that will bring opportunity to all players, to be in charge for their own MMR progresses (current system seems to be locked for most players in terms of increasing their MMR-s)

    What needs to be done, in order to achieve those goals:
    * calculate MMR-s for each player individually, with consideration of their in-game effort
    * under term "in-game effort" should be considered statistical world averages of most criteria (ex: KDA, Total DMG, pushing, supporting fighting, GPM, XPM and etc...)

    So, I think MMR calculations should be done by principle of reduction.
    Every game must impose MMR CAP-s for win and lose for both teams.
    MMR should be calculated for each player individually, with consideration of their in-game effort, hence player in the loser team, who played very well and showed good results in comparison of world averages in the same MMR and with the same Hero, will take less penalty as of -MMR, rather than taking full -MMR as others in the same team, and vice-versa in case of winning.

    Team_A (average MMR - 3800):
    win_cap = function() {some function that calculates win_cap} // lets it be: 35.5
    lose_cap = -Team_B.win_cap // -22.5
    Team_B (average MMR - 4100):
    win_cap = function() {some function that calculates win_cap} // lets it be: 22.5
    lose_cap = -Team_A.win_cap // -35.5

    Lets imagine Team_A loses, but one player in the Team_A, who played with Crystal Maden, did a great job in all aspects of game, had a better results in KDA, GPM, XPM and etc... than world averages with CM for same MMR, but hes team lose and as a result he got same -MMR as others in them team.

    with this new MMR system, algorithm should calculate whole impact and performance of that player and as a result, lets say, he performed 40% better then world average CM player in same MMR.

    For that reason, with new system, MMR for that player will be:

    calculated_MMR = Team_A.lose_cap * (100% - 40%) = -22.5 * 0.6 = -13.5 MMR

    but for another player in the team who performed, lets say, worse than standard by 10%, will get whole lose_cap without adjustments.

    So, in short, player MMR-s will be calculated individually, with consideration of their in-game effort derivations from the world's statistical averages of same Hero in same MMR.

    Advantages of new MMR system over old one:
    * completely self-controlled, dynamic (without any statically defined components) system
    * motivates players towards their best play, and mitigates general abuse level in community
    * player dedication is granted with a real chance to increase their MMR

    This will be unique, universal, ideal and best MMR system ever.

    thanks and sorry for my English

    The only issue with the MMR ranking system is that we don't have the ability to lock out certain regions from being matched with us........Do that and I garrote that the MMR issues will be fixed because %90 of the Peruvian player base will never see anyone from the US servers again
