There is nothing really major here for moonkin but there are some interesting things in the patch currently on the PTR. If you would like the full patch notes and a list of undocumented changes I recommend looking at here at MMO Champion.
Genesis: Now works with Tranquility and Hurricane. - This effectively does nothing for moonkin. This talent still sucks. If I want to buff hurricane I will pick up Gail winds.
Nature's Grace - Now also effects Revive. - A half second off my 10 second out of combat rez? Whoopie!!!!!!
Starfall - Will now be cancelled by any shapeshifting. - Is this really necessary? Is it really a bad thing that I can shift out and heal while Starfall continues to tick? I just don't see the point of this one.
Remove Curse and Abolish Poison can now be used in Moonkin form. - This is really nice. I am currently the only raiding druid in my guild. We usually have shaman to clear up the poisons, but there have been times when I've had to do it on 10-mans or heroics. It will make my life easier.
Glyph of Focus - Increases the damage done by Starfall by 20%, but decreases its radius by 50%. - The general design idea behind glyphs has been that you gain something at a cost. In my opinion this glyph is pure win. I have actually been fairly frustraited with Starfall. It is our new "dumb" spell, because I have little control over who it targets. I can't use it much on Malygos because it will kill the sparks to early. I have the same problem on Loatheb. I can't use it on trash at all because it is likely that I would pull a pat. This glyph doesn't cure those issues but makes them easier. In reality though, none of this matters. Moonkin already have 4 very good major glyphs available to us. I don't see my self giving up the MF, SF or IS glyphs for a glyph to improve Starfall.
Glyph of Typhoon - Reduces the cost of your Typhoon spell by 8%, but it no longer knocks enemies back. - This glyph does improve Typhoon from a PvE perspective, but the spell is still pretty bad, therefore there is no real use for this glyph.
* Tapping: All player spells which cause a creature to become aggressive to you will now also immediately cause the creature to be tapped. - This is an awesome change. It won't mean much for Graylo since Moonfire is the best mob tagging spell around, but my two main alts are a shadow priest and an affliction warlock. The mad leveling rush is over, but this should make their lives easier when content is released in the future.
* The run speed in spirit form has been increased by 50%. Night Elves in Wisp form will now move at 75% speed. - WOOT!!! Faster corpse runs. The also added 60 grave yards to vanilla WoW.
* Alchemy - All flasks no longer require an alchemy lab to create. - Not a surprise, but I wish this had happened a little sooner. You don't need a lab for the new flasks already, but if you read my last post you know that I am not able to make any of the new flasks yet. So, I have opted to use the old flasks for the time being since Fel Lotus is very cheap right now and it still persists through death. It would be nice to not have to go to shattrath anymore but I am sure that I will be using the new flasks by the time this patch goes live.
Whats Not in the Patch:
In general, I'm pretty happy with how Moonkin look and with Wrath of the Lich King in general. Most of the things I would like changed aren't huge, but I have come across one issue recently that I can't for the life of me understand why it has not been fixed.
Where did all of the gem crafting patterns go? I was trying to gets someone to cut a [Purified Twilight Opal] for me and I come to find out that it is impossible. Its not that the gem isn't in the game, because it is in the game files. Its just impossible to learn. Really, how hard is it to put all of the gems in the game? I realize that the blizzard employees are busy people but this is just ridiculous.
