No. Instanced MMOs place people in the "open world" by design, not by choice - that very fact is what makes them an MMO, the lack of choice in who is sharing your world. They don't need to be in a party. That would be Diablo 3, where only people that [b]choose[/b] to join [b]you[/b] show in your world. Again, educate yourself. [b]Guild Wars[/b] is an MMO that does this exact thing. Social spaces. Missions exclusive to you. Open world "patrols" where other players exist outside of your party, sharing the instance. Get. A. Clue. Your attempt to merely get the last word is rather pathetic.
