The problem with the lack of co-operative play (apart from the inherent benefits of playing with friends that ZedsDead listed in another thread) is that survivors are too well rounded. In a real-life disaster/apocalypse there would be certain skill sets that would be incredibly valuable: - Medical training such as doctors, nurses, paramedics, even vets. - Mechanic/engineers, who can repair and maintain vehicles, generators, machines, etc. - Survivalists who can hunt, track, find fresh water, orienteer, build shelter, etc. - Farmer who can grow and prepare food, and maintain livestock. - Military/police, who are trained marksmen and can use and maintain any type of firearm including military hardware. - Pilots All of these skillsets would be highly sought after, and you'd be lucky to know or find someone who can do even one of these things, since most "city folk" like stock brokers, programmers, accountants, etc probably wouldnt have any of these skills. And yet in DayZ survivors can do all of these things perfectly. They're like one-man-armies. As such there is no need to seek out other survivors for aid (and we're not even talking about the crushing fear of loneliness when people think the endtimes are on them and they seek others out for companionship). When a survivor can do anything and everything then there is only risk in meeting other survivors, and zero reward. Its a system that only benefits the anti-social lonewolves and bandits. Every survivor's value only amounts to what gear can be picked off his corpse. Whereas in reality it would be a person's skillset that really mattered. You wouldnt be so quick to shoot that guy down on the road if you thought he might be a doctor who could set that broken leg for you, or someone who could give you shelter from the freezing nights, or teach you how to clean and shoot that rifle you found. I dont know if a class system is the answer. But possibly spawning with a single random skillset, and then slowly "learning" additional skills from other survivors as you spend more time around them. Afterall, once you've survived the apocalyps for a few years with other people you'll certainly have picked up some new skills and tricks. Maybe thats whats needed to slow down the mindless shooting currently: value the person, not their beans.
