Perk Suggestions
Went through the Perks in the game and stringed together how they interacted with game mechanics and how they did so.
The following are suggestions Perk ideas I concluded were lacking derived from that:
Survivor Perks:
A Perk that allows the movement/creation of Totems.
A Perk that allow Survivors to interact with their Blood Pools (EG: Throw a line of Blood the way you're facing while Injured).
A Perk that interacts with Breakable Walls in any manner.
A Perk that allow the limited and restricted creation/rearrangement of Pallets.
A Perk that allows the movement/creation of a Chest.
Killer Perks:
A Hex Perk where the Curse effect spreads across Survivors like a plague.
A Perk that allows the movement/creation/direct interaction with Dull Totems.
A Perk conditional on Blood Pools (EG: While standing still for 2s near a Blood Pool you see the Aura of the nearby Survivor for 4s)
A Perk that allows repair progress redistribution of a Generator (Akin to how Potential Energy allows progress consolidation, but the opposite)
A Perk that relocates Scourge Hooks.
A Perk that provides an effect when Endurance is consumed on a Survivor.
