I have concerns about this. I have never had a gain in hunting or any combat skill, in spite of killing and harvesting many many creatures. I'd hate that because I'm not constantly fighting, or just a non-crafting PKer, what skills I do manage to gain in those areas, will be dwindled because I am busy helping my tribe do constructive things around the camp.- Stat gain and decay system. This is a gradual gain and decay based on what skills you use. The system is designed to adjust your stats over time and has limits to prevent advantages from grinding.
