I have been five boxing a Prot pally, rogue, hunter, mage, and resto druid, They all have their own individual names and I have done BH, FL, BWD, BoT and DS around 20 times, I have only been told once that I needed to leave for multiboxing, we wiped in BWD on Nef because two of the healers,(not even my resto druid) went to the wrong pillar three straight pulls. "Oh hey he is multiboxing this fight is to difficult for a boxer lets ki8ck him."

Beyond that my comp can run 8 copies of wow with no slow down so I am told more often than not that people dont even noticed I am boxing.
