What if WoW would be cancelled in a week and your guild would move to another game as whole with different kind of social/guild tools altogether, would the guild itself survive the switch?
What if WoW ceased to exist, would the guild you are in survive and find a new 'home' in another game? Providing of course that the guild has own forum and/or other means to stay in contact outside the game.
Just some what if's to think.
