Lets make this..
If your bored as hell without your friends or You want to finish this quest ALONE..
Rather make 2 servers with the same contents...
1st one is the Single Player Server where you and only you can play inside it.. No one will bother you there..
2nd one is the Multiplayer Server where you can meet your friends and do quest with each other...
Think of this.. If this would happen, people will go here even all the players in other servers will see this and I would really love to play this (even im stuck in bat quest)
