In particular, I think all three of the new feral druid talents sound great, though Lunar Inspiration is my favorite just for concept alone. The restoration druid options aren't quite as exciting, in my opinion, though they certainly aren't anything to sneer at. The other classes I play regularly are my frost mage and my retribution paladin, and a few of their talents strike my fancy as well--Comet Storm for the mage and Empowered Seals for the paladin in particular sound fun and useful, respectively.
Have you looked over the talents in detail? Some haven't changed much since BlizzCon, but some haven't been documented publicly until now. What do you like? What don't you like? What do you wish were there?
