At least the Glyph is very optional for PvE, so you can keep yourself as a Moonkin in raids. Still, in PvP I think it will be a must to blend yourself a bit in the BGs. Probably there will be cries about how is this, but the druid community warned the potential issues and no one heard us, so... *goes to the store and buys some popcorn*
What I'm more impressed about is the Glyph of Moonbeast. Cast all heals without dropping the shapeshift?! I don't think this will go through the beta, and if there are not other glyphs that can provide comparable utility or situational powerups, this will be a real must, specially when paired with Dream of Cenarius or Heart of the Wild.
