Ok, to start with, lets analyze when Lunar Shower would be a dps gain, and when it would be a loss:

Gain: When you have to continuously move for longer than 4.5 seconds, are outside of eclipse, and have no issues with overwriting the current dot on your target.
Loss: Whenever you wish to remain at a specific energy level, especially for multidotting purposes. Dots and shrooms are almost 60% stronger while you are in eclipse so in any scenario where there are multiiple mobs in range at the same time, you wish to stay in solar eclipse to spam dot/shroom. Lunar shower interferes with this and pushes you out of solar (or wherever you wanted to be) so you cannot keep this up for longer than 20 seconds, give or take, and that is with a full solar bar.

Let me list out the Dragonsoul encounters:

Morchok - too long, will describe in detail below.
Zonozz - as you mentioned, obviously there are plenty of tentacles to multidot. Preplant shrooms to burst down the flail then multidot boss/claws/eyes.
Yorsahj - multidot forgotten ones mixed in with shrooms. Don't tell me you've never had back-to-back black oozes, which means you have to stay in solar the entire time they're out.
Hagara - multidot frozen bindings and ice tombs.
Ultraxion - the one fight where lunar shower is not a dps loss. It is also not a dps gain.
Warmaster - given that there's generally 4 and up to 5 mobs up at any given time in phase 1, it's best to simply stay in solar for the first three minutes of this fight.
Spine - ideally you want to stay at 75-80 uneclipsed solar the majority of the fight, moving into solar just as the amalg goes nuclear so you can start burst on the burning tendons with a fresh solar + nature's grace.
Madness - regenerating blood is obviously a multidot scenario, along with blistering tentacles on (generally) at least one platform depending on your order. Also a dps loss during just the two-target phase, explained below:

Lunar shower on two targets:

In two encounters in Dragonsoul (Morchok + madness), you will be engaging two high-hp targets that ideally you'll keep dotting up. In my experience, I've found the best times to refresh dots are: 1.) entering solar, 2.) exiting solar, and 3.) in the middle of lunar. There will be a slight clip when you apply dots as you exit solar, but especially in the two target scenario, the extra eclipsed dot uptime more than makes up for it.

How solar eclipse looks like without LS:
Enter solar, dot up both. 100 energy.
7 wraths or starsurges, taking you to either 1, 3, 5, or 7 solar energy depending on how many ss procs you get.
Dot up both, then exit solar.

How solar eclipse looks -with- LS:
Enter solar, dot up both. 92 energy.
6 wraths or starsurges, taking you to sub 13 solar energy.
Dot up both, then exit solar.

In the scenario with LS, you are casting one fewer eclipsed wrath, along with clipping your dots earlier, both of which are dps losses. You may cycle through eclipses very slightly faster, but your ratio of eclipsed hardcasts vs non-eclipsed hardcasts falls because you only want to reapply dots during eclipse (and thus eat up energy there) in return for the extremely minimal initial damage bonus on moonfire/sunfire.

I have personally experienced the first seven heroic modes in this raid zone and I can tell you straight up I would never consider LS in my spec.

Edit: as far as normal modes go, all of the previous statements apply as well, with the exception of Morchok and Zonozz. They become straight up single target fights like Ultraxion, where lunar shower is neither a dps gain or loss. Using moonfire/starfire during movement in dragon soul is always a dps loss (shrooms are about 4x as much dps), so there shouldn't ever be a time on those bosses where you're re-casting moonfire with the lunar shower buff active.

I was lucky enough to obtain Will of Unbinding this week and thought I'd share something I saw.

Wild Mushroom and Typhoon both add a stack of the buff per target hit and Starfall adds one stack per wave per target. So the usual pulling with shrooms and Starfall (assuming you're not heading towards Lunar first) can get you a 10-stack very quickly at the start of an encounter.

Sadly it doesn't refresh from DoT ticks but the actual casting / refreshing of a DoT will (I'm thinking about things like Black Blood of the Earth, where mechanics force you to move and forsake hardcasts).

EDIT: I recall reading somewhere that the next haste breakpoint this tier is 3101. Is anyone able to confirm this? I have determined that I can just (literally) reach this breakpoint with the VP trinket and changing Lavawalker -> Haste, but I want to know for sure this information is accurate first. Thanks in advance! I would be running with Will of Unbinding and Bottled Wishes in place of VPLC, if that affects the outcome at all.

And finally - Merry Christmas and a Happy New Year to all feathery laser casters out there!

The WoU mechanic actually benefits DPS casters in an unorthodox way, it hinders healers from using the trinket by keeping a DoT up on the boss. Otherwise its exact mechanics don't really have much influence on it being BiS as a Moonkin - as long as you can attack something, it'll stay up.

As for the haste breakpoint as well as the second trinket, https://docs.google.com/spreadsheet/...KPti9oE#gid=22 is a good resource for all haste breakpoints, including the mentioned 3101 breakpoint for NG without DI.
However Bottled Wishes is horrible and you'd lose way more DPS using Bottled Wishes plus changing your enchants than you'd gain from the breakpoint, not to mention it's not even a breakpoint if you have DI.

It's not the definite answer to all trinket questions but my SimCraft results I've already linked two pages ago (Simulationcraft Results) are probably the best general estimate on the trinkets you can get and it shows just how bad Bottled Wishes really is.

Thank you Hidden, those two spreadsheets were exactly the sort of thing I was looking for. I read the thread before replying but I guess I missed your link, so apologies for overlooking that.

Guess I'll just have to keep my fingers crossed for the Insignia!

It can also proc when you're DPSing and cool down while you're not, which would amplify it's potency, rather than reduce it. You call that RNG and it averages out in most cases.

As for CotC, single target it's actually a worse version of VPLC. The proc of 410 CotC is barely better than that of 384 VPLC - the only reason that trinket is better than 397 VPLC at all is its passive intelligence. As soon as we have multiple targets, it's obviously best in slot though.

I've been using AskMrRobot and it gives me a specific list of BIS, giving the resto chest as BIS (which it is) but it shows Lightning Spirit in a Bottle as the best Relic. However, when I change the relic to Mindbender Lens, it gives a higher score value-- 53229 to 53293--so what the french toast?

Hello guys!
I just got the Cunning of the Cruel (LFR) atm I'm using normal VPLC and DMC:V but I dont hit any haste breakpoint, I was wondering if CoC(LFR)+VPLC would be a better combo than my actual one. I even have enough vp to buy the Bottled Wishes but I dont know if it's worth it..

Don't forget haste breakpoints. Light Spirit has no haste, while Mindbender Lens does.

I don't know how AskMrRobot works, but even WrathCalcs could give similar results if you use equivalency point values. For example, +1 haste rating might be worth X, while +116 haste rating may not be worth X*116.

hi everyone and happy new year !

I've been trying spine 10 hc and i have some question for that burst moment on the tendons. I'm using 2T12hc+2T13hc + craft pants + valor point trinket so i can reach 3400+ haste without problem but here is my question... is mastery better for burst dmg moments ? I'm starting full solar eclipse saving NG, placing 3 mushrooms for instant +dmg spell debuff and most of times i don't have time to reach lunar before tendon close so i'm about 60% of time in solar eclipse ( depends on Tarecgosa procs). either i don't have time to refresh dots. I've been thinking about reaching 3101 haste cap and then mastery but i don't know if i should just replace all my haste for mastery or keep going full haste... Btw is there any program that can calculate that exactly moment ? Thanks !

I am fairly certain in this situation that Mastery will surpass Haste, when I've been doing it it feels closer to 80% uptime of Eclipse during the tendon phase. You spend 4 globals before you start Wrathing (Starfall, Detonate, IS, SnF), and it feels like only 2-3 uneclipsed Wraths hit the tendon with travel time.

Well the last thing I do before the tendon spawns is drop Treants then IS a random blood or high tentacle, that way the IS on the tentacle has NG; I could Starfall in between Treants and IS but then you are talking about losing 3-4 seconds of it which seems sketchy.

Also the only way you can get close to Lunar Eclipse is if you don't reapply when you are leaving Eclipse which you should since IS also buffs Wrath with the 2pc. Mastery was close enough to Haste anyways, I'm pretty sure it pulls ahead in 23second burst rotation w/ 70-80% Eclipse uptime depending on how fast your staff takes you out.
