Wow, that is awesome.

Did you go enchanting across the board just for +24 spell damage (+12 to each ring)? If so, sounds kind of crazy though I can't argue with the results.

Edit: Ugh, you have more armor than my pally tank, lol. I also notice you only have the Medallion of the Horde on one toon, is that typical when you fight and is the one your "main"?
