EDIT 1.17.11: Stat values have changed slightly, but the general order remains the same. I will try and update these numbers soon.
***********************************************
Influenced by Gilga's resto post, I just wanted to post some relative stat values for the Fire Mage.
Intellect 3.96
Haste (until 516)
Hit 3.1209
Spellpower 2.6208
Crit 2.2168
Mastery 1.4517
Haste (over 516) 1.3722
You can use this to evaluate gear, and even whether or not it's worth it to get a socket bonus. Here's how:
If a piece of gear has a blue socket with a +10 Haste socket bonus, you can either:
- Put in a +40 Intellect gem, ignoring the socket bonus, and the value would be: 40(3.96) = 158.4
- Put in a +20 Intellect/+20 Hit gem, getting the socket bonus of +10 Haste, and the value would be: (20 x 3.96) + (20 x 3.1209) + (10 x 1.3722) = 155.3
Since 158.4 > 155.3, the socket bonus is not worth getting. You would use the pure Intellect gem.
Suppose we change the socket bonus to +10 Intellect. Is it worth it now?
- Put in a +40 Intellect gem, ignoring the socket bonus, and the value would be: 40(3.96) = 158.4
- Put in a +20 Intellect/+20 Hit gem, getting the socket bonus of +10 Intellect, and the value would be: (30 x 3.96) + (20 x 3.1209) = 181.2
Since 181.2 > 158.4, the socket bonus is worth getting. You would use the +20 Intellect/+20 Hit gem.
