So.... that Thana buff tho

The major strategy against both Legion and Plague is no heal so buffing Thana changes up that part of the meta. If you don't like it just heal.

The problem is that the killers who actually need that help aren't going to use Thanatophobia because they can't reliably get value out of it. It's too dependent on how survivors choose to behave, and most killers don't have a strong enough 1v4 that having several survivors injured at once is something they can ensure. Like, Wraith likes having injured survivors and is good at landing the first hit, but trying to do hit and run in the CoH era results in a lot of chases and very few downs because everyone runs off to self-heal as soon as you drop aggro. (Which incidentally makes nerfing Self-Care pointless, when CoH is still miles better than it anyway.) I'm not saying those killers can't get everyone injured, but by that point, they're usually already winning the match and Thana is an afterthought, not something they used to propel themselves to victory.

I don't really see anyone spending a perk slot on Thana now that they wouldn't before - it's still Legion, Plague, and the occasional stacked slowdown build with Penti and/or Dying Light. People might mix it up with the new Gift of Pain for a bit to see if that's any good? But it's generally going to be same-old-same-old. It's just that Thana is now more annoying than it was before, which was already pretty annoying.

Ironically I went against a plague on the PTB but she didn’t use thana

I'm general I agree, since some killers are just downright better at hit n run than others, but I think there are enough killers that could get enough value out of a single injury now that the values are as high as they are, that combined with sloppy and a hemorrhage add on, would justify buffing the perk in this way.

COH is annoying, and can severely hamper hnr, but it also requires survivors to go out of the way to utilize it, which can inversely benefit the playstyle. Self-carr made this worse because you could too easily hide near an objective while healing, or just not be, the killer would never know, and thus unless they have nurses, just lose pressure without any prior warning. At least COH has caveats, just healing wherever, combined with healing efficiency on green medkits if you so choose, are busted and kill hit n run way worse than COH can alone. With the hits it took, now survivors can still remove pressure at their own will, but unless they corral themselves to a specific area or want to waste 1/3 of a gen healing, they will have to find others, and combined with chase efficiency being buffed across the board, these small instances can and will add up.

Completely agree.

Tbh, if they really wanted to buff thana for the killers that can’t get much out of it right now, what they could’ve done is make it not a flat value per stack. So for example you could get 6-6.5% for one survivor injured, but then each stack after that is worth less. Fine tune the numbers so it ends up being the same (or even slightly weaker) on plague and legion with everyone injured but overall slightly better on pretty much everyone else. That way they don’t need to increase the maximum penalty beyond 20%.
