Thanatophobia change has been announced
"Following the Mid-Chapter Update, Thanatophobia quickly rose in popularity, and it’s easy to see why. Between the increased numbers on the perk itself and the longer baseline generator repair times, Thanatophobia now slows down generators pretty significantly. Particularly with Killers who have an easier time keeping multiple Survivors injured (e.g. Legion, Plague, etc.), this could make Thanatophobia feel a little oppressive, especially when paired with other slowdown perks.
To address this, Thanatophobia will be receiving a rework in the 6.1.2 Update: Each injured, dying, or hooked Survivor will now provide a 1/1.5/2% action speed penalty. If all four Survivors are either injured, dying, or hooked, Thanatophobia grants an additional 12% penalty to Survivors’ action speeds.
This change will make Thanatophobia nearly as potent as before if all Survivors are injured but will require more effort on the Killer’s part to get full value.
1 surv injured = 2%
2 surv injured = 4%
3 surv injured = 6%
4 surv injured = 20% (12 + 8)
I think this is a healthy change personally
