Killer skill check perks should be buffed

I purchased doctor recently and I was excited to try a skill check build since he's so check heavy. However, through playing, I've found that a lot of the skill check perks aren't nearly as useful as just straight up running the same perks as every other killer.

Huntress Lullaby gets cleared before its power actually comes into play.

Unnerving Presence doesn't seem to slow down survivors at all. Even when paired with distressing to maximize the range, gens pop as normal.

Overcharge is the only one of the skill check perks I have that does anything on doc, and it's better paired with Pop than the other perks.

Doctor has an opportunity for really cool skill check builds that would make him stand apart from basic killer builds of bbq, pop, corrupt, etc. But all the perks available don't do nearly enough to slow down survivors, unless they're players who already have trouble with skill checks, in which case you don't need the perks.

Huntress Lullaby should be de-hexed and unnerving presence should be severely buffed. Survivors should actually fail skill checks if I'm using multiple perks that make them harder. Or the skill check system for gens should be reevaluated. It sucks that this build is entirely non-viable.
