Sure, but even with those previous numbers you listed, your moonfire should effectively be just over 2200 dps. There's no way removing it should be even close to improving your dps.

With your approximate stats I'm seeing a 90dps difference between SF+MF and just SF using my simulator (DrBoom).

Yeah, it's a little standalone dps simulation app I wrote (should be releasing an updated version today).

And yeah, 2200 effective dps -- using the earlier numbers of 679 average with 439 ticks, and 240 haste. Thats 2874 damage from a single 1.3 second GCD, or an effective 2200 dps. Obviously that relies on letting it tick out so you can't simply spam it and do 2200 dps, but you're getting 2874 damage from only 1.3 seconds of casting. You need to have a higher effective dps than that with just starfire spam for removing it from your rotation to increase your dps.

And of course your moonfire damage will go up as your starfire damage goes up, so it's unclear to me that there's ever a point where removing it from your rotation makes sense.

A new versoin of DrBoom, my moonkin dps simulator, is available:

DrBoom 1.0b released - Deus Vox Guild Message Board

What's New:

• Added "Self Drum?" for calculating GCD used if you are one of the members of your group using drums.
• Added support for multiple heroisms/bloodlusts.
• Added two more cycles (MF+IS+Wrath and IS+Wrath).
• Added two more trinkets (Glowing Crystal Insignia and Vengeance of the Illidari).
• Changed raidbuffs to be multiplicative with gear/talent buffs, not additive.
• Fixed some tab-cycling order issues (though it's still not quite right).

Awesome simulator! One thing that is bugging me though is the large crit % on starfire. I entered 18% crit and the simulator has me critting starfires 32.59% (instead of 18+5.9+4=27.9%) of the time. Where is all that crit coming from?

Edit: Ah nevermind, i had 4pc T6 checked, my bad. =P

The following might be the cause of your trinket woes:
1) Moonfire crit rate is 4% too high as the crit rate is 10% over base crit and not 10% over starfire crit. If you look at the results, you can see its always 10% higher. (Helps lit cap a bit)

2) The crit % in the field should be without the 5% from moonkin aura(and obviously, should also not include totem of wrath). If you include these in your base crit rating, it will also make the lit cap even better.

3) Are you manually adding/subtracting the stats you'd get from the skull/hex head when switching to/from it? This would explain the sim favoring the statless trinkets(I'm not getting this same problem with my gear setup)

4) Lightning capacitor damage does not seem to get hit with the 6% resist every other spell gets. Since the other procs affect our spells directly, this might favor the lightning capacitor some more depending on how that damage is calculated. Probably not as much of an issue though.

Moonfire crit rate looks good to me. Base + 4 (focused starlight) + 10 (imp moonfire) + 5 (moonkin form) + a little if you have Idol of the Raven Goddess.

Yeah that's true -- is it possible for that trinket to partially resist? I didn't think it could so currently it just has the base 1% binary resist rate (assuming you're hit capped). If it can, that's an easy fix.

Focused Starlight does not affect Moonfire.

I'm currently at 1595 +dmg full raidbuffed/wrathstacked, and just picked up the T6 pants/legs a week and a half ago. I'm about to regem for +haste, since I only have 68 right now, and can easily get much more than that. I know that above 1110 or so, you want dmg to equal haste. However, I was trying to figure out how much of a gap there would need to be for a +10 haste gem to outweigh a +5haste/+6 damage gem, assuming the socket bonus is irrelevant.

It's the same thing. You're trading 1.2 spell damage for 1 haste in either case. If you want to be exact, it's actually 6 damage before, or 1386, but it's about the same either way.

Oh, ok, I was trying to figure out if there was ever a point where 1 Haste = 1.2 Damage in terms of DPS increase

So you are saying if I have 15 Reckless Pyrestones = 90 spell damage and 75 haste - that means I can get 1392 - 90 = 1302 spell dmg as the base cap for spell dmg 1:1.2 haste rating?
