It seems the game reduces MMR if you surrender as a killer

I played a match for the Spirit, the survivors did not touch the generator for 10 minutes and I surrendered, the next match I played with completely new survivors with basic skins who generally didn't loop as well as the previous team. It seems to me in this case MMR dropped a lot, because the difference in opponents was too obvious!

I also surrendered when three survivors fell during altruistic actions, and again I noticed that even in this scenario my MMR seemed to decrease again because again there were weak survivors. Please fix it, killers can abuse this to mock newbies, that is, slug or hold generators for 10 minutes
