Ghostcrawler graced the WotLK Beta forums over the weekend and had this to say regarding Improved Moonkin Form: (link)
"The plan is for it to go raid wide.
Given the talents avaiable to deep Balance, I hope it's obvious that we are trying to make the Moonkin a very competitive spellcaster. Some of the concerns from BC (e.g. running out of mana, lack of AE or CC, not enough group synergy) should be aleviated by now."
This is pretty big news for moonkin. I have been wondering if Moonkin Aura would go raid wide. Since most other buffs are now raid wide it only makes sense. Why would you bring a moonkin who can buff one party when you can bringa shaman who will buff the entire raid.
I have to agree with Ghostcrawler, in that Blizzard has addressed a lot of our traditional issues. Our mana regen is good, we have a repeatable (but somewhat underpowered) AoE, indoor CC, and improved raid viability. I think most long time moonkin will agree that these are good changed that address our main Pre-WotLK issues.
However, I am still nervously awaiting the Balance Revision that sounds to be almost complete. What are they going to do with Earth and Moon? Are they going to do anything to improve Eclipse? Are they going to do something to reduce the bloat in the balance tree? Stay tuned. As soon as I know something, you will see it here.
