As far as the humanity system goes, people will be more inclined to work together more when the zombies are actually a threat to be considered. Hordes of zombies, different types of zombies like runners, and just overall better AI is all going to be implemented in the game at a later time. When that happens there will be more opportunity to help other people, but right now killing other players is the only thing to do in the game. It's the whole point. You get guns, ammo, food, water, medical supplies, then what are you going to do? Just wonder around the barren map and kill the zombies that pose no threat at all? If that's what your playing the game for then maybe this isn't a game for you. I bought this game because I love survival games. Just being put in a world and the whole objective is just to survive, and part of survival is knowing who you can trust, which is where your friends list comes in to play. Everyone else is a potential threat. That's how it would be in a real life apocalypse, and that's how it should stay. You can tell who is going to be a shoot first person just by watching the way they play. If they got their gun out at a ready position, then it's a pretty safe bet they won't be friendly to you. Wise up a little bit or you may want to look into a different type of game.
