After beeing a long time leecher i try to contribute something.. searched and dont found anything about this.
If you kite Ai-Ran The Shifting Cloud (which is a lv 91 Rare in the Vale of Eternal Blossoms) to Shrine of the two Moons (Horde) or Shrine of the Seven Stars (Ally) he will kill every afk player with his Spinning Crane Kick.
He is casting this AE very often and can only be interrupted with stuns. Its doing a high amount of Damage. So kite the mob to a player and wait there (he is doing low meele damage) until he is casting his Crane Kick. Then run away and watch them die. The guards wont attack the Mob, and dont run to far away or he will cast Chi Blast which hits realy hard.
have fun doing this. (:
