I wish there was a way that I could opt out of other players being able to shoot me and I being able to shoot them. I don't like that the players just sit and wait to ambush you no matter if you are geared to the hilt to kill zombies or if you are a fresh spawn just trying to make your own way. I don't think players should have the option to shoot me if I am brand new to the game and not as good as these pro-murderers.
