I heard only K2 has taken it. We are trying it tomorrow on K10, we did a test run a week ago and got it a little under half before too many people lagged out and we couldn't kill the healers anymore.
You will need at least four good alliances rallying on it I think, we have six or seven. Then all alliances rally at once, have reserves at the temple to kill shaman and reinforce rally. Good luck.
All warfare is based on deception.
Know thy self, know thy enemy. A thousand battles, a thousand victories.
The supreme art of war is to subdue the enemy without fighting.
