Holy Shield (spell)
Consecration (spell) -- yes, it does miss, but the combatlog doesn't report it.
Until you are hit capped, hit is a very good stat for threat. I would say STR and BV are better, but hit is a solid 3rd. Expertise is 4th until you start to get close to the block value cap for ShoR (probably won't happen in progression tanking gear), where it becomes 3rd. Hit will actually surpass both STR and BV once you are capped for the BV portion of ShoR. You should take a look at some of Theck's plots. They are pretty informative.
Also remember that hit scales almost exponentially with level difference. An example of this would be that level 82 mobs only require around 6% spell hit to cap, while level 83 mobs (boss mobs included) require 17% spell hit. Melee hit is a bit more relaxed, but still jumps between level 82 and level 83 mobs. You will most likely not miss often on trash but can on boss mobs more than your think due to low hit.
That said, I wouldn't stack hit/expertise, but discounting them can be as big of a mistake. Each stat has its place.
