SBMM is not working as Intended

As a killer main that won most matches before without sweating and while almost never tunneling, I have not changed my playstyle, I still play really chill and yet I am only getting absolute sweat squads every single game. In 5 days of test, I've only gotten matched with 1 single survivor that wasn't very good. All other survivors were of incredible skill, while I was playing low tier killers like Pig, Trickster and Wraith.

This would be expected if I was playing Nurse or Spirit, but this isn't what's happening. I'm not playing sweaty and playing low MMR killers and yet ONLY get matched with very high MMR opponents.

This has really burned me out, having to sweat my life off for a game which I never did, only to get a 1 or 2k.

This is the first time I'm considering uninstalling the game as every game is just really unfun.... (Also the killer q times have been horrendous, 15+mins queue times)

TLDR: Playing super chill should give me super chill opponents, NOT sweat lords every. single. game.
