I myself have alot of spare time to play the game. I enjoy playing and it could certainly be seen as an addiction. Although I consider camping NM's for 24 hours a waste of my time, there are other players that enjoy it. I think fights that showcase your characters strength as important. Obviously there are at least 2 players that think long time camping NM's is enjoyable. Maybe SE could put a few of these NM's in game to appease the players that enjoy long time camping.
