Need for mid-game collapse
I'm being partially facetious. But, there is a serious problem in this game that has never been addressed since its launch. Most any killer can testify the irritation of the game being held hostage by hiding survivors. This is obviously only problematic when you have two or more remaining survivors. It is further issue when the hatch has yet to spawn. Sure: let them regroup to heal, cleanse totems, search chests.. but something needs to be done once they still refuse to work on generators.
The obvious solution is that, if no generators are being worked on within X amount of time (say, two minutes?), then survivors begin to get idle crows, and/or their auras revealed. Again, proposing this only for two or more remaining survivors. If they literally cannot do anything else but work on generators, then make them do so. Don't waste a killer's time.
