OP are you so addicted to the game that you have to play it until the last minute the servers are scheduled to go down and then get all worked up because you did not get enough in game warnings?
I would advise you seek counseling on videogames addiction.
Well this thread went a bit off the rails. To the OP it might have something to do with being in an instance when it happened. I'd bug report it. It's doubtful that they purposefully misled you on when the server was going to be going down.
