Killers should be able to see the aura of the hatch when there's five or four gens remaining
First, I am a survivor main.
Before the end game collapse update survivors use to have to complete two generators before the hatch would even spawn.
So my idea is that if the survivors were unable to complete two generators the hatch would show it's aura to the killer. This mechanic is already in the game as Bill's perk Left Behind, so would be simple to implement.
If the game is going badly for the survivors, the survivors don't really have an incentive to work on generators as the Hatch will spawn anyway.
As a survivor main I would not have any issues if this was implemented as the survivors failed to do their objective. The advantage the killer would have with being able to see the hatch aura is a reward for preventing the survivors from doing their objective.
EDIT: Due to some confusion. The hatch would still have the same spawning requirements. However, when the hatch spawns with five or four gens remaining, the hatch will show it's aura to the killer. This would create an incentive for the survivors to complete at least two generators before the second to last survivor dies, to prevent the killer from being able to see the hatch's aura. Therefore, the last survivor will have a higher chance of a getting a hatch escape.
