I don't understand. You advertise a "Mega Mission" to everyone of all countries well in advance. Fine. But then y'all whine when people show up to try to kill you. IF you don't want any opposition (which would be boring like offline play) then why advertise the mission to other countries? IF you DO want opposition then why whine when it shows up? You're throwing out a challenge and then complaining when you're taken up on it.
I look forward to your missions, I simply don't understand why you expect no one to come looking for you or how it could possibly be any fun if no one did.
