I don't know where these numbers are from, but if you take the BoK in account, wouldn't the new improved word of fortitude (don't know the spell in english :x), which gives +4% stamina, be part of the calculation ? Or maybe it doesn't stack with MotW :/

So in a brief skim, I couldn't find how the 40% AP -> 36% bonus damage (glyph) change roughly effects Feral dps?

It's a buff until you reach an AP level that's not obtainable in WoTLK gear. And assuming this game lives that long the numbers can be tweaked again.

+40%AP = +30% physical around 9k AP.

The 6% from the glyph pushes it up to an insanely high number.

White:
(54.7+AP/14)*1.36 = 54.7+1.4AP/14
AP = 6892.2
Mangle:
((54.7+AP/14)*2+634)*1.36 = ((54.7+1.4AP/14)*2+634)
AP = 46834.2
Shred:
((54.7+AP/14)2.25+742.5)*1.36 = ((54.7+1.4AP/14)2.25+742.5)
AP = 48472.2
Rake:
(AP/100+190+1161+AP*.18)*1.36 = 1.4AP/100+190+1161+1.4AP*.18
AP = 63994.7
Rip:
(.3AP+3204.3)*1.36 = 1.4*.3AP+3204.3
AP = 96129

Aside from white hits, I'd say "insanely high numbers" is an appropriate description.

It's going to be weird not having the Mangle Glyph, but then, it's going to be nice being able to break 6k on a single target.

I just notice people always talk about Hit and Expertise, but what about Armor Penetration?
Now that bosses have 13083 armor wouldn't It help melees achieving a better DPS if they Armor Penetration were higher? (maybe considering they are hit/expertise capped)

No because armor pentetration only affects auto swings, mangle, shred, and ferocious bite (if we even use that anymore). 40-50% of our damage will be from bleeds (rake, rip) so it's only common sense that a stat that wouldn't affect half of our damage be not as good as stats that do (ap/crit).

The "common sense" assumption that armor penetration is balanced around players whose damage is 100% mitigated by armor is wrong.

Rogues, DKs, hunters, ret pallies, and enhancement shamen all have components of their damage which isn't affected by armor. The only class with nearly-pure physical DPS from my guild's last WWS parse is our Fury warrior, and he still had plenty of Deep Wounds damage. Other physical-damage classes/specs can range from 20% (warrior) to 60% (DK) non-armor damage. 40%-50% is middle-to-low value on the scale, but it's not terrible.

If you haven't realized it yet, armor penetration isn't our worst stat on Live (see haste and crit) even in non-FB cycles (see Toskk's, Rawr). On live I'm quite happy seeing it on gear, because it's both a good secondary DPS stat and it doesn't have a hard cap on its value like hit/expertise.

Of stats to change, Haste is what gets hurt the most in the conversions: our autoattack damage is by far the lowest of everyone's as a percentage of our damage, since the SR change buffs yellow attacks while nerfing white, and the shred glyph means we get more yellow damage since less energy is needed to keep up Rip.

Overall though, I expect ArPen as a stat for us to stay slightly behind where it goes for all classes: if it's a slight buff on average for every class, it'll be neutral versus live for us; if it stays where it is for everyone on average, it'll be slightly worse.

Will arp be additive? I know that it is if you look at the box in-game, if I have 11% arp from gear I get 61% when Grim's toll procs (49% from Grim's toll)

Will it stack that way with sunder & faerie fire as well?

I'm considering buying a nobles deck while the fair is up. But I would really like to know if I should go with agi or strength.

I understand as of 3.1 agi > str for cat dps. But im concerned about the proc itself. Lets say my trinket procs after I rip or rake. Does the crit gained from the agility buff apply to those 2 bleeds?

Nightcrowler's initial analysis of the current PTR build for feral dps shows armorpen tied with Agility in terms of dps contribution per point. I don't see Blizzard going forward with the changes to armor pen as it stands currently, especially considering it's the only stat that gets better the more you have.
