Found an interesting item where the hit rating on it is bugged, parses for more dps on my DK so might as well take advantage of it.
I was doing Free at Last - Quest - World of Warcraft <--- this quest and I chose the Liberator's Blade (Liberator's Blade - Item - World of Warcraft) as my reward. At the time I was using Axe of Frozen Death (Axe of Frozen Death - Item - World of Warcraft). When I switched from the Axe to the Liberator's Blade, I went from 182 to 282 hit rating. My skill on both weapons was capped, so I found this odd, since my net gain should have only been 36 hit rating.
When I logged out and logged back in I lost 64 hit rating. Unequipped the sword and re-equipping it gave me back the 64 hit rating.
I have tons of hit rating gear and wasn't able to get anything like this to happen, only using the Liberator's Blade, and my DPS on Recount reflects that the hit rating does take effect.
TLDR: The Liberator's Blade (Liberator's Blade - Item - World of Warcraft) from the quest Free At Last (Free at Last - Quest - World of Warcraft) appears to be giving about double its stated hit rating.
Here is a pic of me with my original Axe of Frozen Death:
And here is one with the Liberator's Blade equipped:
Hope this helps someone out there.
