Stat Priorities

I've decided to throw together an assortment of current class priorities, I will be just doing the classes I play, and will +rep to anyone who helps me out with this compendium. This information is up to date as of 4.2.

Death Knight:

Frost:
Strength > Yellow Hit to Cap > Expertise to Cap > Haste > Mastery > Crit
Not much to add here. Ignore socket bonuses and gem 40 strength, unless there's a socket bonus of 20 strength or more.

Unholy:
Strength > Hit to Cap > Haste > Mastery > Expertise to Cap > Crit
Ditto.

Blood:
There's no definite priority, as exists with dps classes. The best you can do is experiment and see what works best for you, this is my recommendation:
Enough health that you can survive 3-4 hits from a boss. This is referred to as the stamina soft cap.
Mastery, a lot of it. It's more consistent than dodge/ parry.
Keep your dodge and parry as close to equal as possible, as they both suffer diminishing returns.
With hit and expertise, I avoid it as much as possible. My knowledge is limited strictly to 6/7 ten mans at the moment, but I never have any issues holding threat. We regain the runes we lose if our attacks miss, or get dodged/parried, so all we lose is a GCD.

Hunter:

Marksman:
Agility > Hit to cap > Crit > Haste to 12.98% > Mastery > additional haste
The reason you only want 12.93% is so that you'll never fall bellow the GCD cap (1.0 sec cast time). Mastery will outperform haste in any aoe situation. Gem straight agility, unless there's a 20 agility+ socket bonus.

Survival:
Agility > Hit to cap > Crit > Mastery > Haste
This one is pretty straight forward, imo. Gem straight agility, unless there's a 20 agility+ socket bonus.

Beast Mastery:
N/A. You shouldn't be raiding as BM.

Druid:

Feral dps:
Agility > Mastery > Crit > Haste > hit/ exp
Don't go for the hit/ exp caps. Gem straight agility, unless there's a 20 agility+ socket bonus.

Feral tanking:
Help?

Resto:
Intellect > 2005 haste > 916 haste > mastery > Crit
Use any amount of spirit you feel comfortable with. Don't add any haste past 916 until you can get up to 2005. Gem straight intellect, unless there's a 20+ intellect socket bonus.

Rogue:

Assassination:
Agility > Spell hit cap > Mastery > Haste > Expertise to cap > Crit
Not much to say here, Crit and expertise suck, avoid them. Gem straight agility, unless there's a 20 agility+ socket bonus.

Combat:
Agility > Yellow hit > Expertise to cap > Haste > Spell hit > Mastery > Crit
Another very straightforward stat priority, love playing a rogue. Gem straight agility, unless there's a 20 agility+ socket bonus.

Subtlety:
N/A. You shouldn't be raiding as subtlety.

Mage:

Arcane:
Intellect > Hit to cap > haste to soft cap (1.0 cast time on Arcane Blast with BL/ cooldowns up) > Mastery > Crit
There's a lot of debate about the arcane stat priority, but this is what I've found to work best. If you're really interested in the couple hundred dps you could gain by truly individualizing, run 'er through a spreadsheet. Gem straight intellect, unless there's a 20+ intellect socket bonus.

Fire:
Intellect > Hit to cap > Haste > Crit > Mastery
Gem straight intellect, unless there's a 20+ intellect socket bonus.

Frost:
Help?
