Currently for now the worst perk's for survivor's and killer's
It's just my opinion:
Killer's:
Monstrious shrine - The number's of percentage are just too low, perk is just terrible
Surveillance - 16 second's for looking how the generator's are pretty in white 
Fire Up - Same with monstrious shrine
Insidious - Perk which promote's camping and gen rush
Thanatophobia - Same with Monstrious shrine and Fire Up
Spies from the shadows - It was only good before 1.4.0 patch
Unrelenting - Yes I know it's for beginner's, but this perk is really not worth a slot
Play with your food - 15% of movement speed is pretty good, but you must waste so much time to get the token's and ''lose'' obession
Dying Light - Promote's tunneling, camping and also gen rush. When you finally kill your beatiful obssesion the exit's gates are opened so it's kinda useless
Stridor - Counter for iron will, but have the same problem with Monstrious shrine
Territorial Imperative - Not really a good perk,even for Nurse and Hillbilly
Beast of Prey - The cooldown is too much HIGH, also removing the redstain doesn't help so much in the chase's
Hex: Huntress lullaby - It shouldn't be a hex
Survivors:
Hope - Not really worth a slot perk, your movement speed will be slightly faster for limited time and only work's when the exit gate's powered
No one left behind - Bloodpoint's for the altruistic action's are only increased when the exit gate's are powered...it's not really a good perk
Open Handed - It's a good combination for the perk's such as OoO or kindred, but 8 meter's is just too little.
Slippery meat - After the rework, it's still just terrible.
Up the ante - The number's of percentage are just too low...
This is not happening- after the buff is still terrible, cause it only work's when you are injured and the great skill check success zone is only slightly increased.
Resilience - I would personally just removed increase the number's of percentage and removing affected interaction speed from generator's. It also shouldn't only work when you are injured.
Alert - You see only the killer from 36 meter's for 6 second's with cooldown, it's still better than dark sense but it's still weak
Technician - Is just terrible
Vigil - After the exhaustation nerf it's useless
Spine chill and Prenimotion - it's only good for beginner's, but those perk's are really weak.
Left Behind - No comment
Saboteur - After so many buff's for the hook's it's not worth to running it anymore
