I just realized that Death's Verdict is alot better now and I'm pondering if I should start using it instead of Sharpened Twilight Scale. Trinkets with agility (either proc or passive) seem to be rather good atm. I'm waiting for Yawning to update Mew so I can se how the DPS buffs have affected stat values. After that it shouldn't be that hard to determin what trinket to use. Really quick napkin math would suggest DV actually beign better, but at this point I'm just making guesses on the stat values.


STS
65 Mastery rating (reforged)
98 Crit rating
Proc for 1304 AP
+Higher item level
+crit can be reforged to mastery
-weak stat on proc

DV
288 AP
Proc for 510 agility
+incredible proc (over-itemization)
-Lower itemlevel
-poor static stat that can't be reforged.

I toyed with this idea as well, except i was comparing death's choice normal vs deathbringer's will heroic. DC normal's proc actually wins out, but the mastery/crit pulled dbw hc ahead of dc normal. In your case it's different tho; using Mew to calculate values based on my current gear (crit capped, as much mastery/agility as is possible to get), you get the following stat values:

dv hc:
288ap * 1.25 from aggression * 1.145 relative stat value = 412 dps
proc = 603 dps
total: 1015 dps

sts normal
65 mastery * 2.75 relative stat value = 179 dps
98 crit rating * 1.88 relative stat value = 184 dps
proc = 382 dps
total: 745 dps

It might be slightly different for you depending on your gear, but I don't think any gear would make enough of a difference to make a ~300 dps difference in trinket values.

Although AP cannot be reforged, it's item budget value is higher than that of crit rating (since you get 2 ap for 1 item budget value, putting ap's relative value item budget wise at 2.29, compared to mastery at 2.75 and crit at 1.88), so the passive stats aren't that far from each other.

A new version of Mew just came out and using the stat values heroic DV does seem to win even against normal STS a little bit. The newest Mew did have some issues though. Rake had an old formula and there were some other anomalies, but I doubt the stat values will change too much. I also realized that DBW isn't that good anymore even with the amazing agi proc since it's only a 1 out of 3 chance. Right now it seems like DV (heroic) > STS (normal) > DBW (normal). These are the trinkets I have access to right now. I'll do some more research once Mew gets a new version.

Edit: I don't think you are suppose to multiply relative stat value with aggression. I think it's allready in there.

It's kinda buggy though. I managed to get it to work only after I placed Ravage directly somewhere on a bar (hidden in the corner).

You have to press the macro twice to charge & ravage, but you can charge, use some other skills to consume energy, TF and then Ravage with 15% damage buff.

With the newest version of Mew and my approximate stats I get the following results.

DBW (normal) = 1031 avg (794 - 1276 depending on what procs)
STS (normal) = 1150
DV (heroic) = 1269
DV (normal) = 1122

So if the Mew data is accurate looks like Heroic DV is one sweet trinket.

The relative statvalues I got were:
Agi 4.87921
Haste 2.041
Crit 2.129
Mastery 4.035
str 3.389

With my current gear, I cannot get H DC to model higher DPS than my H STS. DC also loses a lot more of its benefit if you're not using the proc (due to moving, etc...), whereas passive crit and mastery are very good right now, so I'd be hesitant to use DC over SHS in most situations. At least for me, it doesn't even look like swapping would benefit me on certain fights due to crit cap (H DBW in second trinket slot).

H STS (reforged mastery):

DPS: 17837.6
Crit Rating: 1246
AttackPower: 504
Mastery Rating: 595
RSVs: Agi = 4.57, Str = 3.2, AP = 1.52, Haste = 2.05, Crit = 1.94, Mastery = 3.89, Hit = 2.73, Expertise = 2.75


H DC:

DPS: 17795.65
Crit Rating: 1135
AttackPower: 864
Mastery Rating: 522
RSVs: Agi = 4.52, Str = 3.15, AP = 1.5, Haste = 2.07, Crit = 1.94, Mastery = 3.94, Hit = 2.77, Expertise = 2.79


TotT, Unholy Frenzy, Shattering Throw, and Dark Intent not checked.

In regards to opening rotations - I've been running a FC - Mangle - Roar - Shred - Ravage (should be 4cp's now) - TF - Rake - Rip - continuing from here as we always have. Anyone see any problems here? I know I'm losing the 15% buff to that first shred but i'm using it to dump energy before the TF (you could switch the ravage and shred to better accomplish this but instead I only spec'd 1 of 2 stampede) and then using the guaranteed Ravage crit for automatic 2 cps, and a GCD of energy regen going into that TF in which immediately getting Rake and Rip up and then 3-4 shreds allowing for immediate FB while still at good energy levels. Any thoughts on this appreciated.

/castsequence reset=10 Feral Charge(Cat Form), Ravage

Works perfectly. Shows Charge icon, then Ravage for 10 sec, then back to Charge. Note no space between "Feral Charge" and "(Cat Form)", which may be why it was buggy for you. Spamming it while soloing I am able to consistently get the Ravage in even when it appears the target has turned and I am no longer behind it. I am assuming this is a server lag issue, but a handy one.

I'm not sure I get your point, but 8% hit is indeed needed to defeat a lvl83 boss/mob's chance of missing. This percentage applies to both specials and white swings. I agree with your recommendation though.

Quick observation:

Berserk no longer removes the tiger's fury buff. [edit: removed misinformation]

On a tangentially related note, you can /cancelaura Primal Madness at 0 energy to maximize the energy gain from this talent.

Edit: You're right. Either I imagined it or it changed since I last checked, but as of right now I'm definitely not getting the energy.

Thanks everyone who helped with ideas. But the real deal was in having Ravage spell button (not macro'ed one, directly from spellbook) somewhere on your bars. Try using a macro you like the most (sure, I definitely have alt+1 key unbound) while having Ravage somewhere on a bar and then try remove that spell button off bars. You'll notice the difference for sure. I also updated my previous post for clarification.
