Absolutre Virtue
It was not designed to be invicible, is working correctly, and theorhetically can be defeated. Because there have been so many failures they had planned to show a video of it being defeated. But the team had no time because of developing WotG. They chose to prioritize completing WotG ontime rather than creating the video. But because they promised, a few weeks after WotG release they will begin making the video. They will put up scenes with hints - new hints - that will effect AV in ways that will "blow your mind". (Another media guy says he was told they may release a new item to help as well). There will be no adjutments of AV and it will remain the hardest mob in the game but they are sure it can be beaten. They hope to have video ready before 1st update in 2008.
