I mean... you can tell from the URL... but really... come on now. 36 level 70 elemental shaman? Why would anyone do this with their life? I pray to god for the sake of his sanity that he did not level all of those by himself.. I can't imagine what kind of system he has rigged up to keep them all sync'd together. Does anyone know if there are any publicly available add-ons that provide functionality for this or did he rig up some kind of home-brewed deal?
