On expertise and hit rating

Expertise
- "It is one of the best stats that a warrior can get for both mitigation and aggro."
- "Each point of Expertise will reduce the target's chance to dodge and parry your attacks by 0.25%."
- "weapon expertise ... will stack with any hit rating they already have".
- "a capped hit rating will not be impaired by expertise rating which reduces your chance to be dodged or parried".
- "you need ... 91 expertise rating to no longer be dodged"
- "you need 168 expertise rating to become parry-immune"
- "any warrior that is not parry immune will actually increase their damage taken if they use windfury totem" (it is good for many things, but keep this in mind)

Hit rating
- "...142 hit rating will cap your main hand tanking weapon, and you should not miss".
- "Increasing your hit rating increases your chance for taunt and challenging shout to land on a target. It is currently believed that 1% hit (15.8 hit rating) raises your success rate with taunt by 1%."
