As nobody else did, i want to report a bug that I've never seen during beta-period and that appeared during this first PVP test-period at the very beginning of a warsong gulch.
At the moment the door of the horde castle opened, any players were wondering why they were suffering a corruption debuff. 3 seconds after, an ally warlock took the horde flag.
That means an ally player took the horde flag only 3 seconds after the beginning of the bg, just after having doted any players. He obviously dropped in the wrong camp.
I was waiting for the beginning of this bg 1minute before it actually began and the door opened, so i'm very sure this occured at the very beginning of the bg.
