[General]Cataclysm ratings

Just an aside before I start digging into haste, hit, and expertise - some of the complaints about the previous articles were that the ratings at 82 aren't the same as they are at 85. Which is true, but it doesn't matter as I was comparing them to each other.

If you're curious, the ratings at level 85 have been figured out. You can see the results thanks to Whitetooth over at EJ. They're reprinted here for ease of use at level 85.

Dodge: 176.71
Parry: 176.71
Block: 88.36
Hit: 120.109
Spell hit: 102.446
Crit: 179.28
Haste: 128.05
Expertise: 30.02
Mastery: 179.28

A druid starts with 7.4755 base crit %.
At level 85, it takes 324.85 agility to get 1% crit.

The agility to dodge conversion is unknown at this time.

The important point to note here is that everything stated before was correct. Agility is still 1.8x as expensive as crit rating to get crit. Mastery and crit rating are equivalent, and haste is much cheaper. Hit and expertise are slightly cheaper than haste per 1%.
