Perk Change Suggestion: Unnerving Presence
Perks that make skill checks harder to hit have quite a limited value. As survivors rise in skill, they hit skill checks---even very difficult ones--far easier. Heck, DS has trained them to hit those very tough checks, and now that hooks give skill checks those last few difficult checks are training players from the start. For this reason, perks like Unnerving Presence and Overcharge have a short shelf-life, except in corner cases like The Doctor or 5-token Lullaby, and those are still harder to achieve.
For this reason I propose changing Unnerving Presence.
Lots of perks alert you that gens are being worked on/nearly done, or allow you to regress them, but the trouble is that when you arrive they are often finished in your face--especially if you're a killer without mobility. Thus a perk that slows a gen down based on killer proximity would be great.
UNNERVING PRESENCE
When a killer is 32-17 meters from the hook, the generator speed is reduced by X%. When the killer is 16 meters or less, the speed reduction is instead Y%.
Balance: The reason for two different distances of speed reduction is so a difference between being near a gen and aggressively protecting it--if the killer wants to camp a gen, he's leaving others vulnerable, and approaching to kick it sttill has an advantage over just chasing survivors off. Furthermore it makes the perk less oppressive on maps like Midwich and The Game, where a flat rate would blanket a tight cluster. While it could be argued that this would make 3 gens oppressive, I would argue that perks like Surge and Eruption are already strong 3-gen protectors. Plus the two distances addresses that, as it's unlikely any two gens will ever have the 16-meter range protection.
Also by not tieing it to terror radius, we avoid the Doctor having a field-day with this while slower killers with their smaller TR can have some slowdown--at the cost of the slowdown alerting the survivors they're near even before hearing the TR.
I'm not sure how to make it into 3 tiers, perhaps having the two distances grow to what they're displayed here.
