Getting to the Hit Cap

[Maxion]

Hammer of the Righteous gets deflected, Avenger's Shield can miss if not capped. Hammer can miss too if not capped of course.

My understanding is that:
Hit rating deals with lowering the number of times your attacks misses.
Extertise deals with lowering the number of times your attacks are parried and dodged I believe.

I dont' think there is a stat that will lower your chance to be blocked or deflected since you are making contact like a previous post pointed out.

(edit: I was also shocked when I realized how low the hit cap was for heroics.)
