One more comment. Hopefully the starsurge graphic in the beta now is a place holder. If it is not, I would strongly encourage Blizzard to create another graphic for it. (this has been noted on the beta forums, but there hasn't been an official response)
The current graphic is a noxious large glowing green ball. It's look like sickly swamp gas meandering towards its target, and would be far more appropriate for a warlock (or a truly demented mage) than a druid. Yes, Wrath is green, but wrath is a deep, natural green. Starsurge is currently a sickly, corrupted green. Further, starsurge suggests that it would have some blue or white in it, something along the lines of the colors in starfire, starfall, or moonfire. Maybe two intertwined beams (ah...double helix!), one the color of wrath and one the color of starfire. It is not, after all, supposed to be a pure nature or pure arcane spell.
