The biggest problem with completely removing the option to be neutral is that there are legitimate reasons to be in the op area during the war without being involved in it, for instance digging or training nearby. There needs to be a way to permit this during the war, and ideally during the actual battles, as otherwise some players will be forced to either pvp or avoid useful areas. (There was an op battle recently that I literally ran across because the selection window popped up during my normal activities.)
Also, there needs to be a default option - otherwise players could just move the selection window to one side and remain effectively "neutral" anyway.
