The main reason of making camps will be destroyed. Bad idea. Why players can't just find somebody else's stuff like in real?

If u really want to make this idea realistic you should also think about "blood type testers" (i mean such electronic device) and also if it is realistic u can't just take or drink blood - player need too much equipment. Blood tester, thing to put this blood in ur character - too comlicated for blood system. Sorry for my broken english.
