Earlier today i was playing 2v2 Arena with my arena partner, in Dalaran Arena, there was Hunter and Disc Priest against us.
Pretty easy combo to beat as Rogue / HPaladin but the priest did not fall of the pipe at the beginning and either in middle of the fight when the water came (which should throw you away from the pipe), so we lost because of this bug / cheat... the priest was in LOS for all our CC, no HoJ, no Blind, no Sap, nothing, so he just drank there and was always in full on mana.

Anyone else seen this thing happening again?
