I just spend the last 3 days gearing up my lvl 80 moonkins (only 4 of them, darn RAF thing). They are pretty fun and STARFALL IS OP. Damn that spell is OP, 4 druids aoe face melt with that. Unfortuneatly, once you pop that and typhoon your kinda dead in the water. I mostly just moonfire and chain cast wrath. They are a lot of fun and can totally rape face for 10 seconds every minute which is quite often honestly. They do however really have problems with melee getting in and around them that I have yet to figure out how to deal with.
