I'm pretty sure that's what everyone is saying, that it's now only good on plauge and legion
The nerf is BS
Quit complaining and just adapt. If you were that dependent on one perk then your mmr is probably inflated. This just seems like entitlement.
All that stuff killers said about DH.
It will mean that she's basically always going to have at least one fountain if the survivors want to deny her that perk. So it's gone from being decent on two killers to just being a plague perk.
Thanataphobia 4-person slugs, enter stage left.
You're missing the point. It failed to stop the Thana strategies everyone hated to go against (ie, versing the killers that can perma-injure the team and stack mounds of slowdown on top of that) while killing build variety for the killers Thana was merely mediocre on. It's not a well-executed nerf. To use your Dead Hard example, this would have been like nerfing DH so that it only works for distance... so you couldn't use it to dodge a single hit into a wall anymore, but you could still greed loops with no counter. It killed the meh uses of Thana while largely failing to affect the problematic uses of it.
You're not supposed to do math on 4 stacks because that effective uptime is too low. You are supposed to do math on 1 to 3 stacks.
Stridor is more or less a Spirit perk, so *shrug*
