I would say the slower weapon over the course of a typical boss fight (which I assume Rawr is modeled for) the less impact a slower weapon hitting harder will have.

It all evens out in the end (weapon speed & base damage) which in effect makes the stats more important.

A lot of furys are going for 8% hit and using 20 str and 20 crit gems, doing str>hit 8%>crit>mastery>haste. Can a warrior who has made this work tell me if you aren't completely rage dry? i understand your attacks will do more, but where are your enrages and rage coming from?

The 8% hit is enough to maintain a rotation as long as you don't hit heroic strike too often. If you are practicing on a target dummy it can seem like you won't have enough rage but raid buffs will smooth out your rage income making the rotation much easier. With a low hit build you rely more on berserker rage to keep Raging Blow available.

The current (4.06) system definitely favors mastery over hit, once sufficient rage for the basic rotation is allowed. Depending on conditions (missing the raid haste buff, for example), this might be a little above 8%, and excess hit is still favored over haste. One reason mastery is nearly universally thought superior is the strength of cooldown stacking. Stacking up a strength-use cooldown trinket with a greatly-boosted high-mastery Deathwish, Colossus Smash, and Bloodlust is quite potent. Likewise, the nerfs to HS damage have hurt hit rating's relative strength.

4.1 changes indicate an increase to the relative strength of crit, and likely a slight increase in the relative power of hit. The reason crit is going up (and it was the top secondary stat anyhow) is due to the Colossus Smash nerf, which increases the relative potency Deep Wounds. While the per-point marginal strength of Mastery is going up (going from n+2 mastery to n+3 mastery is a bigger gain than going from n+6 mastery to n+7), the benefits of cooldown stacking decrease and it is likely that the Precision buff will bring white hit slightly ahead of mastery. Haste will probably remain the poorest stat. However, this has not been conclusively demonstrated at this time, and it is possible that mastery will remain stronger than hit, at least once certain levels of mastery have been obtained.

Also of note: hit often seems stronger in dummy testing than in actual raid use, since the stability and predictability of dummy testing allow for more efficient use of HS, while the more-hectic actual raid conditions (as well as damage taken) greatly increase the chance of rage capping and diminish hit rating's effect in practice.

From personal experience, I find my enrage uptime didn't decrease much because when i had a high hit build, my enrage procs tended to overlap a lot more than they do now. Aka before it was proccing when there was still 6 seconds left on the current duration and now procs rarely overlap each other.

A hotfix seems to have altered something about expertise.

An example: I have no gear that has been reforged. I reforge my gear and fiddle with the amount of expertise I have. I log out and then log back in. My expertise has now jumped from 26 to 27 or by about 50 rating (change in rating confirmed).

Is this something new?

Do you have some of the Throne of Four Winds piece? Those are bugged in the character sheet while you're in a city.

No.
As far as I know, Heroic Throw resets your swing timer so using it would extend your 'waiting for rage' time.

Hi there, I'm a little confused about SMF optimizing.
I wanted to try SMF and I thought Hit > Mastery for that spec but then I was parsing WoL and most of SMF top ranked player favorize Mastery over Hit.
Simcraft also tend to favor Hit so I was hoping for some input about that choice and why it seems to perform better ?

I didn't raid enough in that spec to try it myself yet and I don't think dummies would help me much.

It was posted earlier in this thread, the main line of thinking is such - Once you have enough rage generation to use Heroic Strike twice while the the CS debuff is on your target, the value of Hit Rating drops by a fair portion. As well as gaining rage when you hit something though, you also gain rage when something hits you - meaning in some raid environments (many Heroic Mode raids especially), you don't need as much Hit Rating to be able to do those two heroic strikes in the CS debuff window.

The values of Hit and Mastery bounce around from encounter to encounter, but in most fights you will sustain enough incidental damage to push your rage gain to the point where mastery is better.

Another factor that favors mastery over hit is Deathwish uptime - take Atramedes or Conclave, where you're likely to spend more of your time "on target" in Deathwish. So even if hit may sim better, there are many fights in which the scale tips towards mastery.

Decreasing your worst rating and gaining better ones should increase your performance, shouldn't it? Haste increases nothing besides white damage over time/rage generation and it's slighty below hit on rating conversions (120 vs 128 iirc) so unless you're in desperate need of more rage to execute the rotation properly you want as low haste as possible in favor of more benefical stats.
