I would have to say no, not really, this will pretty much kill my guild as we don't have enough active members specifically BECAUSE of the population issues on our server. Getting these people to resub just to transfer characters is not going to be a reality, so I'm SOL. I either stay on a dead server and go down with the ship, or I transfer and abandon everything.
What? sounds like your guild is already dead if most players unsubbed... What are you holding on to?
