What I'd fix and add:
First,
I would like to have an option where Survivors can look like their default skin for the killers. As much as I like the hairstyles for Nea, it's impossible running around with the new pink mouth piece. I love the cloudy pink and the mask, but I don't want to be put at a disadvantage. It might be like "Well, that would be a waste of time" A waste of time the amount of colorful cosmetics that can't be used because it opposes a disadvantage.
To avoid Gen rushing, I'd recommend: 2 people doing one gen is equal to 3 people and 3 people now equal to 4 doing 1 generator. While this might not seem like much, it would go to show that the survivors are wasting their time, doing so. At least 1 of them. If this would come to become, Overcharge/Hex: Ruin would need to be nerfed also, not making the game a snail.
Nerfing DS till it's like a bigger molecule would be great, but making the wiggle 1s faster. Instead of 40/46/52, it should be 34/40/46 with BBQ Chili. I think it should not mess you over as bad as it does. One last thing, Botany Knowledge would be useful if it wasn't 20% but 25%
