To kind of echo what people were saying before:
The short answer to this is: don’t worry about hit. If you are doing your rotation correctly, threat really shouldn’t be an issue. Most people in high end T9 gear are raiding with 30 +/- 6 expertise and 60 +/- 40 hit. It is really NOT A BIG DEAL to be hit capped. I’d recommend looking elsewhere than hit if you are having threat problems because simply put, you just don’t need it. Threat for tanks is interesting because generating 1k TPS more doesn’t really matter as long as it is still higher than the highest DPS’s TPS, and probably won’t be the crux in beating an enrage timer. Threat right now is pretty much like saying, “I don’t have to outrun the bear, I just have to outrun you.”
Many people get concerned that their taunts are going to miss if they don't have high hit rating. This is true, however, it is far better to simply glyph taunt than it is to sacrifice survivability in your gear. If you are doing a fight that requries a taunt to land, just glyph it.
That's taken from my guide in my sig but I changed some of the wording to be more accurate. But basically krc is right, if you need taunt to land, glyph it, if you're not having threat issues, don't worry about it.
Come to think of it, I wonder why I even bother posting in thread's krc has already posted in.... *wanders off*
