I will state a few things quite simply. I have had a private WoW server before. They are quite buggy no matter what you do and unless you know and have damn good coding skills, most of the quests wont work and/or exist. Also, if you say lawsuits have no been successful, perhaps you should read more. While Blizzard has not been able to get the owner's of the servers, they were able to get the server hoster's service terminated, ISP's to discontinue service to the servers and so on. It also can be quite boring when you think about it. Unless you have a few hundred people, it would just be a few people grinding. There wouldn't be any huge raids, auction house would not work too great cause of a few amount of people. Lastly, having a private WoW server IS ILLEGAL! so I recommend not talking about it on the forums here as we are trying to stay legal with everything
