Bullshit mmr

so for context i been playing since shortly after the 1year anniversary of this game. I tried to get my ex into this game and she legit played 6 games on a FRESH BRAND NEW ACC!!! like no joke she did the tutorial then played 6 games. EVERY one of those games was vs a full 4 stack swf. a few of them were lowering their mmr on purpose however some of them were obviously alt acc. like I mean a steam acc with legit ONLY dbd on it or sometimes a hidden profile. meanwhile me? I have a hard time learning new killers bc i will either get baby survivors that dont even know how to repair a generator or i get tournament teams that I've scrimmage against in the past. no in between. the game is either so easy I could do no perks or addons blindness nurse and 4k at 5 gens or they are so hard that I will lose unless I Uber mega try hard sweat. wtf behavior fix this god awful shit
