And I don't see the externalities of this system impacting me via the form of having to deal with 2000s that are actually 1500 or 1600 and kicking them because I don't feel like taking the tragedy of the commons cost of dealing with him ruining 30 games before he has a proper rating while also assuming he doesn't go and farm the old rating back again as fun.
Likewise I don't see games where players 1000 rating above others are around as serious games, nobody is playing them seriously. They're just messing around because nobody wants to tml the 0 rated dude's mexes, arty drop him, strat rush him, etc. The ones that do play it this seriously are the ones then are then either stuck in this loop of only playing these games because that's where their rating came from, risk getting banned for rating manipulation by deranking elsewhere and giving 400 rating to others to spread the problem around, or just ruining 2 dozen lobbies of another game variant. People are just playing as chill as possible. Like just play unrated games if you want to show a guy the game. Or coop, or ai games. Tons of options available beyond harming the integrity of the rating system.
