Hey guys,
a little back story i was in Uldaman and 4 of us died and our priest went on a pillar and kited the boss until we go back. I think this is a bug but im not 100% sure , maybe some1 with more knowledge than me will tell better 
if its not a bug just ignore that… xD
In this video im in STV showing you how to do it. If it is an actual bug lets hope for a fix ^^ because i saw a lot of problems with pathfinding in WoW Classic recently : [
