Almost all of my hours in DBD are from 2018 - 2021. So I apologize if I'm a bit of a moron when it comes to new stuff. I use to split my time between killer and survivor but I tend to play survivor more now. I have no clue what is meta now, so I just run what works for me in solo.

I'm pretty much always running:
Bond (so I can find my team),
Windows of Opportunity (so I can see what pallets my team has used),
Alert (so I can know where the killer is and it helps in chase),
My 4th perk rotates around but it's usually
Deja-Vu (so I can stop 3 gens), Ace in the Hole (because I find it useful), or Any Mean Necessary (because it's fun)

If I were ranking killers 1-5 on how fun they are to go against (1 being fun and 5 being total ass)

1 - Wraith, Hillbilly, Huntress, Leather Face, Oni, Pig, Pinhead, Sadako, Wesker
2 - Nurse, Demogorgon, Unknown, Springtrap, Blight
3 - Trapper, Myers, Dredge, Chucky, Vecna
4 - Freddy, Ghost Face, Hound Master, Nemesis, Plague, Death Slinger, Pyramid Head
5 - Artist, Hag, Doctor, Clown, Spirit, Legion, Twins, Trickster, Knight, Skull Merchant, Xenomorph, Dracula, Singularity, Ghoul (my least favorite)

The only killer I go next to is Ghoul. Sorry if you're on my team and it's a Ghoul but not only is he a boring killer to go against, but his noises give me a migraine. I'll suck it up for the other crappy killers and play the game through but he's my one exception.
