xpertise Cap vs lvl 80 targets: 5% (Dodge) / 5% (Parry) = 20 Expertise = 163.9 Expertise Rating
Expertise Cap vs lvl 83 targets: 6.5% (Dodge) / 14% (Parry) = 26 / 56 Expertise = 213.13 / 459.1 Expertise Rating

Armorpenetration Rating
12.316 ArP = 1% of the target's armor are ignored
Hard Cap 1231.6 ArP = 100% of the target's armor are ignored

Hit Cap vs lvl 80 targets: 5% Hit = 163.95 HitRating
Hit Cap vs lvl 83 targets: 8% Hit = 262.32 HitRating


So basically, hit cap: 8%, expertise cap: 213.3, and what about the ArP cap ?

I proposed to my guild of changing my main from a prot warr to a feral druid and now I'm searching all kinds of information.

Concerning Expertise Cap I will quote myself from the "The Cat DPS Guide for Dummies":


Concerning ArP, what is your question? You just wrote the ArP Cap yourself...

Have you set up a gemming template in Rawr that includes ArP gems?

Well I found the ArP cap rather high, if you want to reach the expertise cap and the hit cap and the ArP cap to maximise your dps, is it even possible?

If you worry with the hit/exp caps, you won't maximize your dps regardless. You should honestly be more concerned with hitting the soft cap for ArP, then working on crit, and getting that to around 60%. That would be a much better dps increase then going hit/expertise. I'm not saying you cannot gem hit/exp, it won't lower your dps per say, it just will not increase it as much as other stats.

I've read your dps guide (got a lot of info out of it, thank you for that) but atm my cat gear sucks, I hope my guild is gonna boost me a bit in naxx 25 so I can get the trinket easily but I'm not sure about that.

What's the soft cap for ArP then?

@Xpr

Reaching hit and expertise cap it's possible but not necessary. Actually the BiS Ulduar gear (without Hard Modes or 10 mens) will push you at expertise, hit and Arpen cap, so yes it's possible.

Arpen Soft Cap
619 with Grim Toll
566 with Rune Stone

and 1231 is the hard cap.

How you play and gear your character is not a choice we make for you.
Rawr is a model, FBN is a simulation so there will be differences. Both of them give similar results and gemming either way will make less difference than how well you play on any specific fight.

I just loaded up my current gear in Rawr twice, in the second instance I changed all of the gems from agility to armor penetration, total gain of 33dps from nine red gems or 3.67dps per gem. Now these values will change based on how much you are starting with but given that both programs base the DPS around a stationary fight, which is far from what most fights are, do you really think you will notice the difference? Being out of range because you ran a different way from the tank to avoid some AoE will cost more DPS than gemming a different way.

Whatever you choose the choice is yours to make not ours.

Okay so heres my question. HOW THE HELL DOES CRIT CHANCE % work?!

All of this is UNBUFFED.

Here's my armory:
The World of Warcraft Armory
My AGI is 1327
My Crit Rating is 669
My Crit Chance in caster form is 22.85%

This is my friend's armory:
The World of Warcraft Armory
His AGI is 1294
His Crit Rating is 603
His Crit Chance in caster form: 36.14%

If my AGI and Crit Rating is higher than his, why does he have 13-14% Crit Chance over me? We're using the same spec, this is caster form, and again, all unbuffed. Rawr also gives very odd stats for this as well.

My RAWR, the only buffs I have enabled is Leader of the Pack:
My AGI is 1423 ....loaded straight from armory btw, newest version of RAWR (2.2.7)
My Crit Rating 681 (12 more than what armory says I have)
My Crit Chance 49.58673%, however in-game i'm @ 52.07% (cat form, leader of the pack, master shapeshifter)
Assuming Rawr DOESN'T add my Master Shapeshifter talent, I'll add it here: 49.58+4% = 53.58% crit chance, which is 1.51% more than what I have in-game.

My friend in RAWR, same buffs enabled etc.
His AGI is 1403 (again loaded straight from Armory)
His Crit Rating 603
His Crit Chance 50.69%


All RAWR modules were used loading STRAIGHT from armory, all buffs STRIPPED besides LotP. Same exact 0/55/16 spec. Does ANYONE have a clue as to
1) Why is Armory vs Rawr showing different stat scores, especially when im loading the Rawr profile from armory
2) Why is his Crit Chance that much higher when I outrank him in AGI and Crit Rating, however when put into Rawr the difference is minimal, and seemingly incorrect. It's bugging me so badly.

I also went ahead and stripped my gear. I'm a NE with 94 base agility, this provides 8.60% Crit Hit Chance. I equipped Infection Repulser (because it has no agility or crit rating) and my Crit Chance is 6.16%.... 2.44% less crit than what AGI says I should have. I appreciate your knowledge and replies as I cannot find it anywhere, and perhaps I've just overlooked it

It's because your friend logged off in catform and you did in casterform.

Concerning RAWR:
I just uploaded your char and RAWR shows 669 Crit Rating (I cant see the strange +12 Crit Rating you mention).
Your Agi in RAWR is higher because RAWR averages the DarkmoonCard: Greatness procc.
Your ingame crit chance shown by your char menu might be 52.07%. However, bosses are lvl83 and you suffer from some crit depression here. That's why RAWR shows 49.53%. If you set your target to lvl80 (in the options), RAWR shows 54.33%
Of course RAWR adds your master shapeshifter.
Again, your RAWR Crit Chance is higher, because RAWR averages the DarkmoonCard: Greatness procc.

Check your weapon skill.
