I think the pvp factor in the game feels unrealistic. People are killing people on first sight (even if its 2km away through a sniper scoop) just for the fun of it and not looting or surviving. I would like more Co-op with strangers, but not limit the free will to kill in game. So, how about: After one or two unjustified kills, you will become a bandit and get a small symbol next to your name or something to help identifying a bandit. And if you die when you are a bandit, you will be looked out from the game for 30min, 1 hour 4 hours or what ever works Then players have the option to kill for loot/fun if they want/need, but will encourage them to play nicely. In a real Apocalypse some people would have no problem to kill for stuff or just fun. But not nearly as many as in the game.
