Wii Fit board to fight the "Body by WoW"
As pointed out by Massively, using the Wii Fit board to control your character's motion isn't going to become the new Warcraft SOP. The video demonstrates that you only turn as quickly as a keyboard turner. Still, for solo questing, it's pretty feasible -- if you could hack your Wii hand controls to fire your abilities. Otherwise, good luck face mashing the keyboard. (I'll let you insert your own OP-class jokes here.)
