From what I've heard, Arcane Power has gotten nerfed. Additionally Power Infusion will no longer stack with it ... I cry myself to sleep.

I didn't look at the other ones, though. I don't have a mage high enough level to much care (31), but I hope they're good changes for your sake.

The Druid change sounds awesome too. The replacement ability for Innervate looks very impressive.
