Since boons came to the game they have been meta shifting, and while I don't think that's a bad thing, I feel they're a bit over tuned right now. My suggestion to reduce strength with out crippling the perks would be to implement a timer that would not allow you to re-boon the totem right away. For example say the killer snuffs the totem, the entity would then block the totem from being interacted with for a time, similar to Hex: Plaything. I think around 30 seconds would be good, giving the killer some breathing room.
I personally like boons, but I can see the power and impact they have on the game, what are some of your thoughts?
