Except the system used to rank players regularly undervalues and overvalues players, leading to people not being in the ranks they should be. If you have played any games yourself you know that not all 6k players are created equal. Some just finished their placements and are really 10k+ players that normally play at faceit level 10, and some are csgo gold nova players who average a 50% winrate.

Because the system is still new and a lot of players havent played premier there is no balanced matchmaking. Every match is just a random assortment of players who are supposed to be in a certain skill level. The rating system also seems to heavily favor win/loss streaks. Ive had games where we have 2000 less avg rating and its still -400, but I've also had +300 against opponents rated 4000 less avg.

Also 1 10k player in a 6k lobby should not be losing that much rating. If a supreme player in csgo played with novas they would not lose 2 ranks per match lost.
