Unknown counterplay
It's simple - you watch at him - weakened disappears.
If you stopped seeing killer - "watching at him" lingers for 1,25 seconds, so you can remove it without struggling with every small texture where killer can hide.
But what if I told you that you can remove it without really watching at him and knowing where is unknown?
As you can see in the video below, you can tilt your camera for a millisecond, so technically you watched at killer and know you get the lingering for 1,25 seconds.
Second thing - you only need to see a part of his body, but how much? - a finger.
I think it's inadequate, so maybe some qol changes for this? like seeing at least 30% of unknown's body hitbox and actually watching at killer at least for 0,5 seconds.
Here is the video that i made with my friend - https://www.reddit.com/r/deadbydaylight/comments/1bn5icl/zero_delay_on_revealing_takes_basically_a_pixel/
