Since 2012, he's slowly but surely leveled his Pandaren Shaman from 1 to 60 without leaving the Wandering Isle. Once he finished the starter quests and outleveled the mobs, he's had to rely completely on herbalism and inscription for his XP influx. He isn't using heirlooms and said he won't play the character unless it has rested XP.
The end result is a level 60 Pandaren that's completely faction-neutral -- and can talk to both sides. You can check out his latest leveling video after the jump.
