Well, when I get home today I'm going to update to patch 3.0.3 and say good-bye to Typhoon. It was... interesting while it lasted.
The primary changes of interest to moonkin are the reduction of Earth and Moon from 5 ranks to 3 and a similar change made to Moonfury. Eclipse was buffed to do more damage and have a longer duration, but I still don't know if I'll take it just because I know that I'm the sort of person who will need a mod to get any mileage out of it. It is possible I'll spec into it once all the theorycrafting is full bore at level 80, but for now while I'm primarily concerned with leveling I don't see any point to it.
The four points freed up from those talents and the fifth since I'm dumping Typhoon are giving me a surprising amount of flexibility at 80 where I'm now considering between Owlkin Frenzy (for the anti-pushback and extra dps when I get splash damage), Celestial Focus (for the spell haste), and even Eclipse (for extra dps). Since I have points to spare after getting all my must-have talents, this means that in all likelihood I will have one of them. The prospect of having that option is admittedly baffling for me considering that there really was no choice in TBC.
A big part of what I eventually choose will likely depend on my experience with the new dungeon designs as I level up, so I'm going to put off deciding on an 80 spec for now.
When I get home today I'm going to go for this: 45/0/16.
I think it'll be good for leveling. Good regen from Intensity and Dreamstate will keep drinking to a minimum and all the key dps talents are still there. I won't have Earth and Moon or Starfall right off the bat, but they'll come with time.
