Which is better for dps, +15 spirit or +10 stats...

15 spirit is better.

A +15 spirit enchant is not strictly better than a +10 stats enchant, but rather the relative value of the two would be dictated by your spec. A quick perusal of the Simcraft thread in this forum for scaling factors tells me that +10 stats gives better DPS for the 0/13/58 build and roughly equal advantage for the felguard builds, in the latter case benefitting from a small boost to DPS from stamina as well. For Affliction, +15 spirit is clearly superior.

It is worth noting that the difference between the two in Ulduar gear, regardless of spec, is probably something in the order of 5 DPS or less. I seriously doubt you would notice it. On the other hand, extra survivability is almost always desirable.

Is there a 'golden rule' when it comes to Decimation(in my case a 0/41/30 spec)? Having issues in regards to keeping a good 1:1 weave. If I have decent range(usually just out of affl range on dots) on the boss I have been dropping everything except immo and incin/SF. Seems like after I refresh immo I have to do a 2x incin to get the weave going. User error or working as designed?

Generally, you want to refresh CoA unless there's less than 20 seconds to live on the mob. Getting MC procs toward the end is still pretty good, and CoA ticks every 2 seconds.

I believe the way to interrupt your weave is to end on an incinerate. This gives you 10 seconds of Decimate to refresh dots, life tap, move, etc. Then restart on an incinerate and use a decimate soul fire right after, this will continue the 1:1 ratio. Technically, I suppose, this still does a double-incin, just spread out in time (you incin, dot, dot, lt, incin, SF, incin, SF...)

I found with Decimation the best way to keep up a 1:1 rotation would be to keep at least 30yd range. Start with an Incin -> Incin -> SF -> Incin -> SF rotation. When you need to refresh immolate/coa/LT make sure you do it after casting a SF, and then start casting Incin -> SF -> Incin again.

Doing this will allow you to maintain a pretty perfect 1:1 rotation.

If I need to spec for Replenishment next week and still need Suppression for hit, where is it generally best to take those 3 points from? Demonic Aegis, Empowered Imp, or the not yet buffed Fire and Brimstone?

I'm using basically the same spec, and for me, the GoLT still gives around 150 SP for 20 seconds. I'll usually try and throw in a LT when it gets low just to keep the constant +150 sp.

Pretty sure I read pyroclasm was the best place to remove points from (until next patch when conflags will be critting at a much higher rate). Found it: http://elitistjerks.com/f80/t48311-s...9/#post1182414

I've searched the thread buy no similar questions were asked.

Shadow Mastery: Increases the damage dealt, or life drained by 15%

Do you actually need to activate this with a shadow bolt? Or is it always active?

According to the talent tooltip, it should simply be an increase in shadow damage/drain life by 15%, without needing to enable it separately with for instance a shadowbolt. The thing that confuses me most is that Dotimer displays it as a debuff with a timer. If I don't cast another SB after an X amount of seconds the Shadow Mastery debuff drops off.

Does anyone know if it infact needs to be 'activated' with a sb or whether it's a dotimer bug? I hope it's a bug cause I'd hate to be obligated to fire shadow bolts during my DS execute for the Shadow Mastery 15% damage.

The Talent "Shadow Mastery" gives you a 15% damage increase, period.
On the other hand... the talent "Improved Shadow Bolt" gives the target a debuff which is called "Shadow Mastery"

Short question. Is it worth using both CoA and corruption in a 0/31/40 spec? Isn't the corruption another wasted GCD because CoA seems to keep MC up pretty nicely?. Didn't try this out in a raid, but I am getting equal dps number on the heroic dummy while using corr, and while not using it.

And how real is the 1:1 weaving on ulduar25 bosses, is it possible to stay at a 28-36 yard range of them all the time? I found it hard to do on the 10man versions, expecially when for example Hodir's NPC drop a sexy +haste/dmg thing just shorter then 28 yards, same with the blue runes on Council.

The real question would be why bother being 0/31/40 in the first place, but if you insist... yes it's worth it to keep corr up, even if only for a marginal increase in MC uptime. If i had to choose only one, i'd use corr to keep MC up and use CoD instead.

The weaving largely depends on boss and situation. From my experience:
Ignis - moderate (depends on raid positioning)
Razorscale - easy
XT - easy
Kologarn - easy if you're not targetted
Council - medium (depends on boss, kill order and positioning)
Aurayia - moderate, depends on positioning
Hodir - hard (also depends on luck)
Mimiron - medium (depends on phase)
Thorim - easy (phase 2 at least)
Vezax - hard (your cast speed will probably be too low for 1:1)
Yogg-saron - should be easy in phase 3, didn't use demo on this fight

Note that "easy" doesn't mean you'll always have a perfect 1:1 weaving, in fact i don't think i ever could maintain one perfectly due to the number of times i had to move.

With 0/13/58 coming into dominance, and assuming hit cap has already been reached,


A) Should I gem for haste or crit?
B) Should I look to the full +16, or do gems that include part Spell power as well?

It really all varies but point for point, haste gives better DPS than crit. On the second one it varies too based on slots and socket bonuses but one valuable thing to know is that 1 +19 sp and 1 +16 hit gives 1 more sp compared to 2 +9 sp and +8 hit gems.

You should always gem for spellpower, unless you are under the hit cap or need to fill yellow sockets for socket bonuses/meta gem requirements. In that case, you would want to gem 9 spellpower / 8 haste, never 16 haste. Haste is significantly better than crit, always gem for haste over crit, but not over spellpower or hit.

To clarify, I have 3 yellow sockets that need to be filled (meta requirements have been met already and hit cap has already been reached) and was unsure whether to use +16crit, +16haste, or their respective +spellpower hybrids. 2/3 of those yellow sockets also have red sockets on the same piece and are gemmed for sp, with the remaining piece being a singe yellow socket, if that helps.

According to supplicium's post deep destro and affliction have very similar stat DPS weighting. I dual speced 3/14/54 and 53/1/17 which brings me to my questions

1) Which 4 pieces of T8.5 are best itemized to get the 4-set bonus?

2) With deep destro is it only viable to use Glyph of Life Tap due to mana inefficiency or does raid replenishment offset
that?

3) Will any Ulduar weapons with +hit be worth gearing around or will Sp/haste/crit 1-hands be BiS? On that note does anyone know how much DPS 1 hit equals (per spec)?

+19sp gems will almost always be best for dps in any socket regardless of socket bonus, once meta reqs are met. The only exception I've encountered is a socket bonus of +7sp, in which case the 9sp/8haste gem (reckless monarch topaz) for yellow or 9sp/8spirit gem (purified twilight opal) for blue would slightly better, depending on spec.

So you prefer the 0/13/58 spec over 0/31/40? I am topping most meters as 0/31/40 so I never bothered looking further into better specs, but is it really that much better?

In theory (and by that I mean through Simcraft and diagrams) the 0/13/58 spec has the highest DPS with T8-equivalent gear.

Ah okay. I can imagine that the 0/31/40 spec might work out better for me, because I am still in mostly BiS pre 3.1 items with just a single Ulduar item. Thought differences will be small, and 0/31/40 has a slightly easier dps rotation I think.

I am currently at 12.96% hit, what should I do? Gem another hit gem to get the last 0.04% capped, or leave it as it is? I think saving a 19 SP gem would add more dps then the 0.04% chance a spell misses right? This is only temporary anyway, assuming I am getting a +hit item in the next reset.
