So a DoT cast during Eclipse retains the bonus for its full duration? (This is what we'd expect based on WLK behavior of DoT's, but wondering if you definitely observed it in Cata).

That would make the most sense. I'm actually curious how DoT refreshing will work into this. It used to be that all hard refreshes (actually recasting the dot) would reset their damage modifiers, but soft refreshes (talents/effects that extended durations) would not. But the question is does the new DoT mechanic still count as a hard refresh or will it be considered a soft refresh?

Finally logged into the beta again and played with some things. Notes:
--Spec bonuses don't take effect until you have 1 point in the tree.
--Eclipse seems to give 25% before you train the "Total Eclipse" Mastery.
--You now can re-proc one Eclipse after letting it run for a full 45s. You can't do it after immediately moving to the middle to end it and moving back. There seems to be a cooldown; I'll try to see what it is.
--Think it's around 30s, might be 45s.
--Best I can tell, E&M is actually giving 13%. They might have put the old spell data line back in.
--Tooltip says each point of Mastery gives 1.5% to Eclipse. If each point of Mastery is 93 rating, that appears to make Mastery very weak.
--Starsurge no longer benefits from Euphoria.
--Eclipse does give 37% after training Total Eclipse.
--Eclipse doesn't fade at 0 Energy, only when you move past 0 Energy, even if you drop combat.
--Confirmed that DoT's retain Eclipse bonus after buff fades.
--Confirmed that Dreamstate is gone. It was a rather small amount of mana before though. The mana scene is still dominated by Euphoria.
--DoT's still aren't affected by haste.
--There is some kind of DoT refresh mechanic though: if I reapply a DoT's that's already there, the tick rate is not interrupted, and I get a bit of extra duration. So I think the best time to refresh a DoT is before the last tick.
--Damage is recomputed on re-cast of the DoT.

Sheet with a few tweaks. Haven't decided how to deal with the DoT thing. Will probably at least compute an average Eclipse uptime and use that for now, but eventually there may be more advanced rotations. In general, something I want to do soon is try adding in some more rotation options.

Some time ago, Relevart posted that energy gains were when you finished casting it (and the 12803 video I saw confirmed it), but in 12857 videos it seems that you gain energy when the spell lands, so my question is: If I'm right about the energy gain, will you gain energy if the spell miss?
This leads me to two more questions:
1. Does the last WR from Eclipse benefit from it? Due to travel time, in 12803, last SF in eclipse benefited from it, but WR didn't. (I think it does now, but it's just a feeling)
2. When does SS check the energy you have? I'll explain myself:
If you are at +5 energy and cast a WR, when the WR lands, you will be at -8 energy, so, what happens if following this WR comes a SS?

• a: SS checks energy when you begin casting it) When you begin casting SS, WR has yet to land, so SS says "you have Solar energy, you'll obtain Solar energy", WR lands, you get to -8, lose Eclipse, SS lands, you get to +8 whitout Eclipse.
• b: SS checks energy when cast is complete) When you finish casting SS, WR has landed, so SS says "you have Lunar energy, you'll obtain Lunar energy", SS lands, you get to -24. (I think this one, but, as before, it's just a feeling)
• c: SS checks energy when lands) SS lands, you get to -24.

Five hours ago, Twigele at simulationcraft posted an update to their cata branch that includes the comment
No explicit mention that this has been tested, but it would be a strange comment to make without testing.
In my opinion, their Balance modeling and theorycraft has always been extremely good.

that seems to make sense, given that my power will decay down to 0 between mobs when I'm soloing, but I still have the Eclipse buff for 1 more cast on the next mob.

Just asked someone who's 85 to test--base mana is 18635.

e: someone sent me a PM with screenshots of two Eclipse procs 21s apart. I'd been almost certain when I was playing with it that was 30 or slightly longer. I'll probably tinker with it a little more--I was thinking there might be something odd going on. People should see if they notice anything.

With Wrath doing more dps than SF and IS dealing way more dmg than MF, there will be no lunar but 100% solar.

When you tested that 30s cooldown, did you ever drop combat?

The current spreadsheet numbers make that a good guess. It might turn out that you want to get back to Lunar just for Starfall, but the gains, if any, would be small.

Also, Lunar Shower makes Lunar very favorable if you have mana issues, or for situations with lots of movement.

Lunar might also be better for for DoT+Tab rotations where targets don't stay alive for very long, although Solar is better for our pure AoE spells (Mushrooms, Hurricane, Typhoon).

I'm highly skeptical that we will be allowed a rotation that enables us to simply hover at one end of Eclipse ad infinitum simply because this seems to be exactly what the developers are working against. Either they're going to make it unfavorable for this kind of rotation to work out or they're just going to make it impossible altogether.
