Moonkin is inspired by the current state of the spec, but is now a brand new spec.
The current spec is based on a cycle of moving a bar back and forth on your UI. You are spending your time playing with the UI rather than the game.
The moving back and forth on the bar is going away, replaced with abilities that build and spend a resource with different strengths and weaknesses.
It should still hit the main Moonkin fantasy, as it is still heavy on DoTs, still has Moonfire, Sunfire, Starfall, and all of the unique Moonkin things.
Innervate is returning, but not to Resto Druids. If they had it, they would want to use it on themselves, which isn't very interesting.
Innervate is coming back to Balance Druids as their specific utility, so they won't have Stampeding Roar anymore.
