Wow Developers’ Twitter Chat, 4/16, about druids:
Restoration druids are actually getting a fair bit. For one, Tree of Life is getting a whole new model (think Ancients of War) and will also “morph” some of your spells to do crazy things while in the form, such as cause Regrowth to be instant, or Lifebloom to apply two applications at once. Tranquility will be raid-wide. We’re also touching nearly every Restoration druid spell to make sure each has a niche and feels good. In general, playing a Restoration druid should feel a lot different (better!) in Cataclysm than it does today.

If the original class preview had said this, I bet there would have been a lot less QQ about tree form. This is telling me that even if we don’t look like trees most of the time, the essence of our tree-ness will still be important to resto druids. Don’t get me wrong I still want ToL a a permanent thing but this could actually be a cool cooldown. I was afraid of a healing boost or haste boost, but this is an actual mechanic change. Very eager to see it in action.
