So, I'm really confused on this boss. I haven't done him in Heroic yet but cleared him several times on normal. And all I do in normal is position my alts, which are all ranged, on the first step and have my tank backed up against his throne. This becomes a laughable tank and spank. This guy is the easiest boss in the instance.

My question is: Is it that much different in Heroic? Does he have some other ability that makes it more difficult? Is the debuff that much stronger on heroic?
