The US-topguild has apparently been permabanned form the Game. As Rumors say about 90% of the players have been removed from the game. Apparently they used a hack to the Client to remove the platfrom of Prophet Skeram in AQ40 to get to C’Thun without some hours of clearing.
While it may seem to be a bit harsh to permaban them from the Game it is the right Signal to give. Using exploits and bugs is simply not worth losing a Character You played hundred of days.
