Thanatophobia right now is pretty much unusable to all killers except for Legion and Plague but even on them it requires other perks/add-ons that it needs to rely on like Legion Pin, Defaced Smiley Pin, and Sloppy Butcher, just to get the most out of it but even with those it can be countered with just 1 person in the healthy state causing the 20% action De-buff to become a 6% De-buff so the only way to use it efficiently is to constantly damage them or give them the broken De-buff.

Thanatophobia Change Idea:

-When a survivor is injured they give all other survivors a 2.5% Action Speed De-buff

-Every injured survivor will receive 5% De-buff instead of a 2.5% Action Speed De-buff

Example:

-1 injured survivor receives a 5% De-buff while the 3 healthy survivors get a 2.5% De-buff

-2 injured survivors will both receive a 10% De-buff while the 2 healthy survivors get a 5% De-buff

-3 injured survivors will all get a 15% De-buff while the healthy survivor gets a 7.5% De-buff

-If all 4 survivors are injured they all get a 20% Action Speed De-buff

This change is to reward the survivors who decide to heal and reward their teammates for doing it, while also punishing the ones who decide not to heal and just slow down other survivors who are both injured and healthy. This is to encourage survivors to heal and not just rush gens. Although this is technically a Nerf to the 4.3.0 Thanatophobia this would be a nice change to both Survivor and Killer.
