If Blizzard have removed the achievement and other bonuses of having the kill, followed by banning them. It is not a world first.Originally Posted by Marrakech
Blizzard have basically said:
You have not killed the boss, a bug has.
Try again next week.
Whilst the ban is a bit heavy, given the unlocking nature of hard modes I do agree the removal of the kill is fair.
They should simply have reset the lich king in the raid id and given them the tries back.
