Can we get some testing with Bone link and Gurthalak with ONLY rebuke, would be amusing to see procs happen since other Classes kicks use up resources and ours doesn't have much impact since it's glyphable.

After spending some time testing the 4 set T13 bonus i can conclude it only benefits damage from activated abilities. Paper doll shows no damage increase change akin to Avenging Wrath or Communion and Seal damage/Ticks appears unaffected.

The tentacle crits with a low, perhaps 5% crit rate, this makes me think of wrath of air totem, is it possible the tentacle is affected by spell aura affects? This would be good news for madness with kalec and nozdomu buffs, and amazing if lust or haste effects would lead to extra ticks.

Could you take special care next reset to see if you gain more ticks compared to number of procs, specifically on Madness.

Suppose you could test on a dummy too and have a lust happen when it procs.

EDIT: forgot those were dummy tests wrath of air shouldn't be there. No harm in testing aura affects however.

lastest simcraft and exemplar still shows crit > haste or haste > crit, one way or the other.

But, they both agree that either crit / haste > mastery, any comments on this?

its either haste / crit getting 1.7-1.8 coefficient and mastery getting only 1.6. should we be looking at going for crit gear now? or is there a miscalculation somewhere?

The 4.3 buffs also value mastery, as both CS and TV will (are) do more damage from the 2h weapon buff.

Tentacle got a drastic crit rework and average damage boost to around 12000

I can confirm this as well although I'm seeing a flat damage of 11378 with no modifiers, this changes to 11720 when an aura is applied confirming it is affected by communion. Crit rate of about 12% so far on raid dummy target and also have not seen it miss yet so that may be gone as well. It is being affected by avenging wrath now as well. The damage boost won't come mid mind flay but it will be updated on the next flay. In regards to the crit I don't believe it is inheriting your melee crit as the percentages I'm seeing are well above what you'd expect when you take my paper doll crit and factor crit suppression(melee or spell).

It could, but I think that back in T11 we had a much larger gap between Mastery and other stats (due to itemization) and it wasn't showing up like that on Simcraft.

While in no way intended as a proper test, I did FL HC and Dragon Soul in LFR mode tonight and got a 23.4% mind flay crit rate, out of 709 total ticks, 216 were crits. Run was about an hour and a half of active time.

WoL page for the tentacle: World of Logs - Real Time Raid Analysis

I figured this might be handy info, especially because it was done in a fully buffed 25 man raid environment.

In your WoL they did 3442 DPS on H Baleroc. On H Ragnaros the procc was worth about 2050 DPS, considering the downtimes in this fight we can expect it's worth more.

On LFR Zon'ozz it was about 5518 DPS, considering the higher uptime of Bloodlust the questions comes up if the ticks are affected by our Haste or if it's only the higher procc chance due to more attacks. Can you make some tests on the Dummy with a Haste heavy build and compare this to your current reforgings?

In 397 gear the 410 Axe is about ~2200 DPS stronger than a naked Gurthalak without any procc when modeled in Exemplar's Spreadsheet without Bloodlust in the Buff section. With Bloodlust it gets closer to ~2100 DPS.

So it seems at a first sight that a 403 Gurthalak beats out the 410 Axe in single target encounters, I think when Exemplar has time to model it he can tell us more.

edit: A further test without any Stacking/Proccing Trinkets etc. could also be very useful to look for the min/max damage of normal ticks. Another test with (a) strength b) int) food/flask could show us if the ticks are affected by it.

edit2: To Eldira: Should only be an example, on heroic shannox it was quite the same in his log

Madness has Spellweave, which procs differently for different classes / specs. Expect QQ about this in the Blizzard forums very soon.
