I'd like to poop on the party a bit. Unless I'm reading this wrong, two things in there deserve a huge /facepalm:
We are planning to remove spells that don't have a clear purpose. Amplify Magic, Dampen Magic, Fire Ward, and Frost Ward are being removed from the game, and we may remove more.
Frost

* Spell damage
* Spell Crit damage
* Deathfrost


Deathfrost: Casting Frostbolt places a buff on the mage that increases the damage for all frost, fire, and arcane spells. The only damage spell that won't be affected by this buff is Frostbolt.
Um, WAT? What more clear of a purpose exists than to dampen/amplify (wait for it) magic?!? Or warding against fire or frost damage? Hellooo?

And LOL @ Deathfrost not affecting the primary frost nuke. Assuming it will even BE the primary frost nuke after all is said and done.
