Killer suggestion
I thought of an awesome killer idea. What about a killer that can react to solely sound like some sort of humanoid mole? When playing its vision would be grey and kind of tunneled and small however it can hear survivors 2x easier (in some cases leaving a different type of scratch mark from noises for it to follow) anywhere from walking to running and if within 32 meters of the killer even slow vaults cause enough noise to give a notification. it's ability could be listening for sounds and getting a direction from anyone making sounds. A new interesting mechanic could be made with generator noise and the speed at which you do the gen and items like fireworks could completely blind the killer whereas a flashlight would not due to it relying on sound instead of vision.
