Here are the druid related questions and answers from Developer Chat:
Q. Is there any ETA on tree / moonkin form graphical update?
A. Moonkin is hard because Moonkin players are so in love with that form. It’s tough to change it at all. We currently hope to do a new tree form for Cataclysm, but no promises.
Q. Has there been any thought of changing Eclipse to charges so that Moonkin dps doesn’t suffer so much from moving?
A. Yes. Expect a major overhaul in Cataclysm that keeps the same basic idea (alternating from Arcane to Nature) but in a way that is more core to the class. Like everything though, there is the risk that we may decide this idea sucks once we see it in action.
REALLY? We love moonkin form? REALLY?
