Did something change? I played a few days after Shadowkeep came out, and while the games were competitive, it never felt terribly one-sided. This week, I’ve been matched against players who are at Legend rank, players who have Unbroken, and I just lost to someone with 76 flawless Trials completions. I don’t even have a positive K/D. I barely scraped to Fabled last season, and have somehow been at the top of my teams - the teams getting stomped - and I’m kinda wondering why. I included a screen cap of my last match, but edited the gamer tags out.
Crucible matchmaking has been adjusted twice now since the release of Shadowkeep. No specific details have been released by Bungie on what the changes entailed, but it definitely has been adjusted at least twice since you played.
