MMR and Gen Rushing is unfair and it's the reason no one wants to play killer anymore

Np :)

Besides the normal "get better" or "play Nurse/Blight" suggestions, there are a few other things that might help you pip while also avoiding high-MMR hell. These are how I got to Iri 1 as killer. If you already know this stuff, I apologize; you mentioned being new. (I also apologize that you got sucked into this game. It is extremely punishing for new players, and honestly I'm not sure it actually gets better once you gain experience.)

One thing to keep in mind is that every killer has their own somewhat-separate MMR. So, if you want to lower your MMR, you have to do it with the killer you'll be playing as. Memeing with Pig to get easier matches as Doctor won't work very well.

I'm sure you noticed that you can depip within a grade but can't depip to a lower grade. So, each time you make it to the next grade, go for a bunch of matches without killing anyone. Killing and killing alone is what raises MMR. Your grade is completely separate and unrelated to your MMR. All that stuff you do to pip, all those hooks you get, those are irrelevant to matchmaking, so feel free to continue practicing and getting better even when you're not killing. Try to enjoy those matches, throw seriousness out the window if you need to and remind yourself it's just a game.

If you're getting matches with experienced survivors despite letting everyone go for many matches in a row, then it's just not your day. Whenever the queue gets long, it starts throwing basically anyone together regardless of skill level to get them into a match. Your MMR becomes pretty much irrelevant when that happens. Unfortunately, this may be the main problem you're running into, and there's no getting around it except playing on different days or at different times of the day.

Yeah, that's cheesing the system, but I see nothing wrong with it when the system is bad in so many ways. The better solution would be for BHVR to improve their skill-based matchmaking system and fix emblems/pipping, but that could be a long time away if it ever even happens, and it's not something we the players have any control over, so in the meantime there's cheesing it.

No one asked, but if you're curious, I reached Iri 1 as Nemesis on PS4 with cross-play on in the North America region (I think East coast?). I used the perks Lightborn, Beast of Prey, BBQ, and either Distressing or Starstruck (Starstruck is good for ensuring you get hooks, but it can hurt the Chaser emblem). No add-ons. In case it's not obvious, that's not a good build. If you equip actually useful perks, you'll make it easier on yourself. Most killers should run at least one gen slowdown perk.

If you don't care about pipping and just want to have fun, then letting survivors go is your best bet to getting better matches. I've had times where I killed one survivor and suddenly my matches were filled with people running the meta. Pipping and having fun in the game shouldn't be mutually exclusive, but in my opinion they unfortunately are.

Like you mentioned, BHVR is testing new matchmaking systems, so if you had good matches before but aren't having good matches now it's hopefully just temporary. BHVR's skill-based matchmaking has been unpopular since the day it released, so I'm kind of glad to see they're working on it but also every time BHVR touches anything I get worried they'll make things worse. All we can do is wait and see, really, and give them feedback when they do these tests.

Yeah, you can be good at killing with a certain killer but not good at pipping with the same killer. It's one of those things that takes emblem knowledge and experimentation. It's a numbers game with needing a certain number of hooks and a certain number of won chases. And of course the Gatekeeper emblem, which benefits from gens going slowly, which is part of why inefficient survivors are so valuable when trying to pip.

This goes towards why I found getting to Iri 1 to not be worth the trouble. Pipping requires dragging out the match to get hooks and win chases while also preventing gens from getting done, which becomes a micro-managing nightmare if survivors are halfway decent. I also had too many matches where someone died on their first hook or disconnected, and then I had to inflate my Chaser emblem by slugging the remaining survivors at least once each before killing them to make sure I minimized the number of points that one survivor cost me. It would happen multiple times in a row, which led to me being quite annoyed that I had to kill to avoid depipping but probably couldn't pip up so I was just increasing my MMR while my grade stagnated and the matches went on for what felt like an eternity. Someone dying early damns the remaining survivors in terms of escaping, but it also damns the killer in terms of pipping. It was a huge relief if I managed to squeeze a pip out of a match with an early death/disconnect.

Nurse is a weird one due to her slow speed. Survivors are constantly gaining enough distance during chases that the game no longer actually considers them to be in a chase, which means the Nurse lost that chase. Then she gets closer and it starts a new chase, and the cycle continues until the survivor goes down or the Nurse focuses on someone else. If you're not a god-tier Nurse getting constant immediate downs, you're probably going to struggle with pipping. (I don't know for sure, though, because Nurse is practically impossible to play on console. I haven't played her since she had that power bar added to her Blinks.)
