Sure, at this time we are being logged out mostly due to bugs, but eventually people will get logged out due to connectivity more than bugs, and when trying to defend a village, that will be VERY frustrating.
As a game where PVP will be important, there needs to be a way for a player who knows his or her password to cut the server disconnect short and log back in. Do not allow a simple "log me off" option from the login page though, logging out should not be a PVP escape. If you want to log back in that's fine, otherwise you sit there till you time out.
