This is what i was thinking about. Mountain Lions, packs of wolves, bears. Me and my team are currently doing the stealth hermit playthrough. we hunt with crosssbows and very rarely run into other players or zombies. Having another danger that could be lurking out in the woods would be great. Also what about having to test waters at ponds and other non flowing areas to see if the water would be potable. That or leeches inside some of the water to add a danger of going in there as well. water would have to be tested before going into it.
