While I agree to a point. They can add a button to have it drop back to the log in screen while still requiring you to log back in. It could resolve the majority of peoples want for a button to change servers. The overall issue I have is that occasionally the game simply wont wanna patch right, or by the time you close out and it launches back in it still thinks you have a client open so it wants to eat more processor and resources temporarily till it finishes closing the game out.

I believe a log out option would not be too complicated. It really has nothing to do with server side at that point. Since the game runs though the log in server, the gateway select server, and then the game server. Going backwards in that would get wonky because of the tunneling. However dropping out to log in should be rather simple to do.
