Saw this idea in the general forums, so credit to whoever came up with it. Since we're going to be dealing with Arakkoa, how about a minor glyph for druids where your Moonkin form takes on the appearance of an Arakkoa.
I already have the Skettis Arakkoa trinket which I love, but once again as druids we get screwed out of any costumes when we shapeshift. I would play Moonkin in a heartbeat on my 2nd druid if we could have this.
