If theres really no reason for you to be in that area in the first place than why would it matter if its blocked off? Its not like its zones, its just a house, a cantina, an opposite classes hangar, or, say a Sith inquisitor building, when your a BH.... No reason to quit, just something unique in the game. You cant simply make a phased area in the game a non phased area for one player, filled with npc's and an instanced for another without instancing the room before the phased area.....
