Everybody knows about it, nobody talks about it
400k HP, 50k xp per kill up to 70k per kill at level 87. With my warrior I can kill one of those each 30 seconds, leveling really fast, and I'm sure other classes can do it even faster. I believe this mob can be totally exploited to get realm firsts, and to be honest I hope Blizzard nerf to amount of xp.
