I don't want to turn the main thread on this into a mage fest, so let's discuss this more in depth here. Specifically, which new spells or quality of life changes make your heart burst with joy?

-For me, the change to ignite(now our mastery, giving a DoT to all DD spells rather than just crits), has a lot of potential. And Fire Spec getting reliable DoT cleaving(Inferno Blast) just makes me extremely happy. The lowering of combustion's cooldown(with a probable nerf to the damage), means you're much less penalized for minor mistakes with it.
-The changes to the armor spells are somewhat intriguing. Mostly, I wonder if their other effects will be worked into baseline.
-Some spells going baseline for all specs make me quite happy as well(Improved Counterspell(!), Shatter, Burning Soul)
-Alter Time intrigues me, though I'm really going to have to see it in action before I can make a final judgment.
So, what are your thoughts? How happy are you for Arcane Orb?
