Okay, tonight I was in Ironforge on my rogue in Ironforge and when I tried to evade some of guards, because I had vanishes on cd... I found very nice spot to "kite" something, like guards or the King.

Just by moving backwards and forwards over the line I made on that pic, the guards starts to run towards and back to old Ironforge. Not sure will the exploit still work that you are able sheep your friend to old ironforge, but the guards just runs to the tunnel of old ironforge from the high seat.
They dont start to evade, but they will start to go around and around just by moving forwards and backwards in that spot.
Would be awesome if someone could confirm this as a hunter or any ranged class. Atleast it worked with throwing weapons on guards.
Sorry for my bad english, but Im pretty tired atm. havnt slept single minute this night.
Oh, btw, heres the location to this place http://img209.imageshack.us/img209/351/asdfesh1.jpg
