The Ultimate Doctor Build
Infectious Fright, Iron Maiden, Distressing/BBQ, Unnerving Presence/Stridor
The goal of this build is to keep survivors screaming and incredibly, incredibly, loud
Infectious Fright: Any survivors within your terror radius will scream when a survivor is downed
Iron Maiden: Exposes survivors that go into a locker and forces them to scream
Distressing: Make your terror radius bigger which will synergize with Infectious and make it easier to force people into madness
BBQ: To get some players at the start to go into lockers to synergize with Iron and for the points. But for the build you may be better off with distressing. It's up to you
Stridor: To make people breath really, really, loud
Map Offering: Lery's, Addons: Order and Discipline, or increased shock range
Survivors will never stop screaming and being really, really, loud.

I don't play Doctor as I find him boring in chases but this sounds very entertaining.
Sometimes when I'm bored I play Doctor just to make the Gens more difficult and not actually try to kill anyone, maybe I'll try this out.
This sounds absolutely hilarious.
It's very evil but really fun. In truth you might want to replace Order with an increased shock field because the Doctor's base shock range is very weak
But oh yeah this thing is fun the survivors will be screaming constantly and they won't know why if they aren't observant
