I'm underwhelmed.

The new spells sound neat but will be nerfed into the ground.
Remember how cool mirror image was gonna be 2 years ago? Yeah,look at it now.
How about FFB, that one was gonna be cool too.

The arcane spec will be dead if the Mana Adept change goes live.Less mana = less damage?
That's like telling a warrior the more rage you get the less damage you do.

It seems like they are getting rid of some of the spellbook clutter by removing some basically obsolete spells, like low level food, amplify magic and the like.Spell ranks will be gone too.
This, I think is a good thing. I have way too many pages to sort through when looking for something and too many useless buttons taking up space on my UI.They could keep frost/fire ward, but I don't use them much anyways.

Time warp? I thought bloodlust was someone else's job. Meh, something else to keep me from casting a nuke.Its not enough I have to move and screw up my rotations every time a boss sneezes?

Wall of fog? Yeah like that's gonna stop a rogue. Not!

I guess I don't see what all the excitement is about.
