I mean, yes it can be i you want it to be and find the right server, but otherwise it is just full of kids who gear up and kill everyone for the sake of killing as it is the only thing people know how to do in video games. I fear the standalone will just end up being a few people who hoard the server and then set out and kill all new spawns. No matter what they do, they will never be able to remove the team deathmatch element that people have brought to this game. Hell, the zombies I doubt will ever be a problem, once those bandits have killed all the zombies what will they kill up until the next restart? all the other players. Personally I doubt dayz will work that well, at least on the public servers.
