...your tuning needs work.
When, as an L78 Affliction Warlock, I can drop into Malykriss over in Icecrown and clear out all the L80 normals without breaking a sweat, you've got some overpowered damage issues. And yes, I do have some heirlooms on, but I also have a lot of L70 PvP gear on.
However, I will give you props for the delightfully insane sounds of the Shivarra. I keep looking over at her, expecting tentacles or something.
