Toon Tweaking Boomkin DPS help!

[Khatovar]

Changes I would make -

Get rid of Dreamstate. You have a whole slew of Innervates to use, there's no need to waste 3 talent points on such a minimal amount of regen.

Drop Genesis. Again, a lot of points spent for minimal gain.

I'm guessing that you're talking PvE and not PvP. In that case, you don't need Owlkin Frenzy. It is only a 15% chance of a 10% boost when you get hit, you should not be getting hit enough to see much if any increase from this.

You probably can drop Moonglow, too for the same reason as Dreamstate.

There's no need for points in Nature's Focus, you should have hit t2 resto off 5/5 Furor and t3 with Natural Shapeshifter and 2/2 ImpMotW.

This leaves you with a ton of points for things you should have.

Nature's Splendor - Extra ticks are extra DPS and with your Glyph of Starfire, you have more time to refresh Moonfire, giving you time for 1-2 more Wraths before you need to switch to Starfire for DoT refreshing.

Celestial Focus - This is free spell haste, and reduced pushback for AOE. DPS boost all around.

Balance of Power - Hit is always valuable.

Improved FF - More free spell hit. 1 can take it to give the hit to the rest of the boomkins. I don't know that I'd suggest all the boomkins taking it for the crit, unless you have nowhere else to spend points.

Insect Swarm - It's another DoT, all your boomkins should have it. Improve it and then Glyph it.

As for gear, Boomkins gear Hit {to cap} > Spell Power > Haste > Crit > Int > Spr. You're pretty much neglecting everything in favor of Int/Spr. If you're running out of mana, it's because you've gotten next to no crit, so you're not getting much in the way of mana restores in Moonkin form.

As far as spell rotations, don't use DoTs on low-HP trash. Lots of trash, use Hurricane or Starfall. Otherwise, Wrath. DoTs won't tick long enough on trash to be mana-efficient or worth the GCD. If you're not managing Eclipse procs somehow, either by toggles or random Wrath x3 -> SF x2-3, then you're just wasting even more points and losing a lot of DPS in the process.
