Last survivor during endgame collapse with closed hatch - really???
Been playing against a nurse and was last survivor.
It's nearly impossible to open gates with a 20 sec time period, given that she can use her perks (murmur), or just use her blinks to quickly find the last survivor, so good luck escaping.
Make it so that when a killer closes the hatch, and there's only 1 survivor, the gates can be opened within 10 sec.
Certain killers can easily counter that with skills against a lone survivor left - Hillbilly with rushing, Nurse with blinks, Doctor with treatment mode.
As well as perks: entity murmur, crows etc.
