Haste at the moment is in a place similar to where Hit rating was a year ago. It's a good threat stat in its own right, but the fact that it's mostly non-existant on tank gear makes stacking it to useful levels an unrealistic task at best.

Wewt! This topic made me fix an error an error on my spreadsheet. For devastate I was using (weapondps+apdps)(hastedattackspeed) for the average attack damage. It should be (weapondps+apdps)(baseattackspeed). |
Actually Devastate uses normalized AP. "(baseattackspeed)" should be replaced by (1.7) for daggers and (2.4) for all other one-handed weapons.

it is arguable that expertise also scales faster than hit. while this is true, it is harder to get than hit, especially after 23 skill so therefore, hit is more viable after 23 expertise. |
Nowadays Expertise is just as easy to find on tank gear as Hit rating, except for the fact that you can gem for +Hit and not for Expertise.
Also, after hitting 23 skill, Expertise's effectiveness at increasing the rate of successful attacks is exactly the same as Hit Rating. In addition, reducing parries can constitute a significant reduction of incoming DPS, particularly vs. bosses capable of landing crushing blows. For that reason Expertise is generally considered more valuable than Hit Rating for raid tanking until you reach the hard cap (~57 skill).
Hit Rating on the other hand has the benefit of reducing Taunt resists, making it more beneficial for 5-mans, raid trash and boss fights where Taunt plays an important role.
