First of all I would like to say that I'm new at this game, (bought it from sale) so maybe this has been suggested/implemented before and failed for whatever reason.
The suggestion is that after a power node gets destroyed, the room stays fully dark until the power node is restored (as dark as it is the couple of seconds after the node is destroyed), this would make flashlights actually useful and give marines an actual sense of being the prey when in dark areas, you could also make a nightvision goggles item which make marines see the room as if it iluminated or something so aliens dont get a huge edge on these areas.
thats it
