I don't believe mangle uptime is quite that simple. If you only landed 80% of your mangles, by your proposed formula the uptime of mangle would be 96%, whereas the uptime would be more like 89% using the trinket proc formulas listed here: Proc Mechanics

You can model mangle uptime as if it were a trinket with a 6 sec internal cooldown, 12 sec duration, attacking 1/6 sec with a 1-(M+D+P) chance to proc. For mangle, it simplifies to 12/(6+6/(1-(M+D+P))).

EditL: Actually, looking over the proc mechanics again, your formula is just the simplified version proc mechanic for mangle as if it had no internal cooldown, which is why it's overestimating the uptime.

My formula was determined numerically and has a very low margin of error. I could be wrong of course, but any modeling I try to do always comes out the same.

Has anyone tested, inspiration and other armor buffs ignores armor cap or no?

No, no armor buffs allow you to bypass the armor cap.

Given that crit immunity can be achieved at 415 defense or 103 resilience, is it safe to say that ~1 point of resilience is equal to ~4 points of defense when combining the two?

Meaning, can I have 380 defense coupled with 10 resilience and be crit immune? I am probably overlooking something because it doesn't sound right.

A) You get 350 def skill from being 350/350 at lvl 70.
B) You need 154 def rating or 103 resil, on top of the base 350 def skill. So for rule of thumb, it's 3def rating = 2 resil, as far as uncritability goes.
C) Just use Rawr, it'll take care of it for you: Rawr - Home

Uh is this new? I don't recall that being the case....

While your number gets bigger, you don't get more than 75% reduction.

No, not new... Whether you have 36k armor or 136k armor, you still only have 75% physical damage reduction.

He probably meant mitigation, which is hard capped at 75% (35,880) armor. Of course the armor value on your character sheet can go higher than this, but it doesn't have any actual effect beyond the cap (aside from exceptional cases such as Stomp).

My bad I misread the sentence I thought the "no no" was together and you were saying you COULD bypass the armor cap

I normally dps and noticed the same problem when I have a bear tank keeping up mangle. I use mangler to track mangles so if the tank misses a mangle, I can immediately (or quickly anyways) throw up a mangle. I figured it is better to apply a mangle myself than to have an un-mangled rip ticking off.

We don't raid with a Moonkin, so thats definitely not it. On our initial attempts, I was in full Tanking gear, with hit around 90ish, since then I've obviously gotten the T6 belt and swapped in a few other pieces of gear, getting me up to 130ish hit for the fight now, with overall more DPS stats. Hell our kill last week we beat enrage by over 20 seconds (5:38 kill, which we lose 4 seconds on the pull) and thats with 8 healers in the raid, but my DPS was down at 757, which is over 50 DPS from my average. I can always squeeze out a mangle/rip stack before having to go back to tanking, most of the time even 2.

But, yeah same results for me... very wildly varying results since our initial couple kills

edit: As a clarification, the 2 at the end of the sentence is used as a number, not a replacement for the word too

A question I have still remains that no matter how many people I ask I never get a consistent answer.
I understand that there is a delicate balance between the two stats but which is better to stack (for sockets and ect.)
Agility or Stamina.
I use 12 stamina in almost every socket. I use a gladiator glyph to remain uncritable and an 18 stam gem on my helm. Every piece of my gear is enchanted for stam with the exception of a few to remain uncritable.
I rescently had a discussion with someone regarding the balance of these stats and which are better, I am now looking for an answer.

The answer for me is easy, every single gem slot I have has agility in it in one way or another for my tanking set. Generically Red = 10 agi, Yellow = 5 agi/hit, Blue = 5 agi/7 stam. I have personally never used a pure stamina gem. Doing this lets me reach a healthy amount of HP, dodge, and even hit at the same time and with the right combination of neck, rings, cloak, enchants, trinkets you can be easily crit immune as well. Example stats for Brutallus after raid buffs is ~24.8k HP, ~50% dodge (does not count SW radiance).

You do not get a consistant answer, as there isn't one. It's open to opinion, and in this thread there's been many examples of the agility/stamina balance controversy. Variables include the encounter, your group/raid makeup, etc...
Read, experience, and make your own decisions. Once you have, post and share on the thread for the next guy.

Why are we quoting 154 as the correct number here? Isn't the math this:

2.6% anti-crit * 1 def skill / .04% anti-crit * 2.4 def rating / 1 def skill = 156 Defense Rating required?

2.6% anti-crit * 39.4 resilience rating / 1% anti-crit = 102.44 ~ 103 Resilience Rating required? (This is correct)

Because your "2.4 def rating" is incorrect. The real conversion number is 82/52*1.5 ~= 2.3654.

^Typo. It's ~2.36538462...

k. I dunno if dukes still updates the front page of the thread but that should probably be noted with a "~=" somewhere.

I think what happened is that the OP hadn't been updated for a long time and said 2.4 / 156. I got confused when I was making my tank suit and asked about it:

Next time Dukes showed his face here, Ast asked him to correct the defense value:

So only that got changed.

Gotcha. I haven't paid attention to the feral mechanics threads in around a year since I didn't realize something had changed; I'm just starting to read them again with the beta and WLK changes in the air.
