Hatch change suggestions?
The killers ability to close the hatch is not ballanced at all. You're lucky to make it that far in a trial to begin with, let alone complete one more gen to re-open the hatch. It will be nearly impossible to get a hatch escape with the killer just patrolling the last remaining gens.
Here are my suggestions on making it more ballanced:
Remove killers ability to see gen auras when one survivor remains in the trial.
Remove the ability for the killer to grab a survivor from the hatch if the survivor has found the hatch first or has re-opened the hatch.
Give the survivor a significant speed buff to completing the gen they need to re-open the hatch.
Hatch can only be closed by the killer once per trial.
Alternative switch for the hatch to be re-opened that the survivor & killer have to find somewhere in the level.
A combination of these suggestions could make the hatch change more ballanced and more fun for everyone.
