Removing guns did part of this, made killing newbies basically pointless, but that still doesn't deter from the fact that the game as it is right now is basically a FFA shooter with zombies in the way. My suggestion is, basically force people to band together. Even if they are bandits. Basically, if you murder someone your sanity goes down. If it gets to low, your character goes nuts and kills himself. The only way to regain sanity is by being near other players for extended periods of time. This way, organized bandit groups still can do their thing, but players that are just playing to kill other players to just be assholes won't get very far. Also bring back a way to recognize bandits at very short range, that way pure survival players can tell if someone has the reputation of being a murderer, but only when you are face to face with them. Maybe have "Bandit" show next to their name or something, but only when you are face to face. This doesn't remove the player killings all together, but should cut it by quite a bit. In all the time I've played this game, I've died to zombies twice, players every other time.
