I have the same on trios. I lose matches after landing for several hours in a row, and the game still places me at the very end on the right side of the graph. I play with the same nicknames every day and every day thereafter. But I won't anymore. EA and Respawn ruined this game in terms of balance, matchmaking and situations with cheaters, where they lost the fight a long time ago.
Today I uninstalled the game, but before I did that I had a game (duo with random) where my companion was an AI bot, and then a level 1 cheater killed me. The next game killed me top1 sparrow PC on cronus zen/xim, because he had no recoil.
This game died and today I finally saw what was going on here. It's a shame - I spent a few years here, but unfortunately there are definitely more cheaters than a few years ago when I started.
RIP my 5000 hours in this game. :)
