when I’ve been playing, the matchmaking was ridiculous. I always play against much higher ranks when I am killer. Please fix this!
I don't see a problem, you have ebony mori.
On serious note, I don't think you always face higher ranks than you. If so, try to turn cross-play off.
You must be extremely unlucky.
You got more points than all of them though even after you mori'd 2 of them which gives you less bp
