In our PvP division of my guild, Conquest (And yes, we are still recruiting for both our PvE and PvP divisions.), we had a new moonkin apply. As someone who enjoys PvPing and tries to as much as possible and reviewing his spec, I thought that I would try to develop my very own PvP spec with what I thought were the major components needed for a PvP player.
Looking through our talent tree, here are the things that I found different from the PvE moonkin spec that are necessary in PvP.
Gale Winds - Increasing the damage of your Hurricane does not do a lot in PvP, but increasing the damage of your Typhoon is huge and necessary. Also, being able to Cyclone at a distance is incredibly important.
Solar Beam - While it may be situational/CC use in PvE, Solar Beam is a life saver in PvP with the ability to silence casters in a huge area.
Fungal Growth - Since we have Wild Mushrooms now, we can set it up to slow people down in PvP besides cause damage. Also, it helps with Treants as well, but in PvP, we would likely use Wild Mushrooms more.
Perserverance - Regardless of which spec you use in PvP, you should always go for this talent. Having 6% less magical damage is huge in PvP, especially when combined with PvP gear.
Of course, these aren't the only talents you will take. You still want to focus on spellpower/intellect and haste talents wherever possible and of course you want to pick up Typhoon and Starfall for PvP. One of the more interesting talents that may look interesting is Owlkin Frenzy. In fact, when making my list, I was left with a choice between Perserverance and Owlkin Frenzy. While a 15% chance of increased damage is nice and no pushback from spells, taking 6% less damage in PvP is more necessary in my opinion.
The other major question of concern is mana. In PvE, mana can be drained pretty quickly depending on your spec. From what I found in PvP, mana seems to be less of an issue. This will also require a few small changes, mainly, the elimination of Moonglow.
So without any further ado, let me give you my custom moonkin PvP spec:
Nature's Grace (2/2)
Starlight Wrath (3/3)
Nature's Majesty (2/2)
Balance of Power (2/2)
Moonkin Form (1/1)
Shooting Stars (2/2)
Gale Winds (2/2)
Solar Beam (1/1)
Force of Nature (1/1)
Earth and Moon (1/1)
Fungal Growth (2/2)
Lunar Shower (3/3)
Total Points: 33
Blessing of the Grove (2/2)
Heart of the Wild (3/3)
Total Points: 8
As I mentioned, there are a couple customizations you can make. If you are really not having any problems with mana, you can go for Owlkin Frenzy, but until gear and mana pools get better, I would hold off on getting that one in favor of more mana return from Innervate.
In terms of glyphs, there are a lot of choices for glyphs, but it probably won't change a lot from PvE to PvP. The one in particular that you may want to change out for your PvP spec is adding Entangling Roots, which makes it an instant cast and may make it useful to set up and keep a caster in Solar Beam.
Hopefully, this will get you started on your way to doing moonkin PvP. It is a lot of fun, from pushing opponents off ledges in AB to keeping a healer under control while you are killing him.
Finally, just a reminder about the Header Contest. This contest will close next Friday so I encourage you to get in your headers as soon as possible.
