When I read about the 7.2.5 quest that places Wrathion in Northrend, and how his excuse for being there was his “own amusement,” this was my first thought.
Once, I even encountered a glitch where my Paladin was booted out of the Class Hall and the NPCs essentially went "Paladin's only" My poor Paladin has never felt so insulted before in his life.
I love the universal MMO communication tool of “jump up and down”
see someone of the same class? race? same weapon? same hat? waiting for the same thing? you jump a couple of times. they jump a couple of times. you both jump up and down slightly out of sync with each other and then wander off to finish whatever it is you were doing
