Maybe I am not understanding the mechanic but how is expertise rated so High? When expertise has no benefit over hit rating when you attack from behind, but gain nothing from a miss; so reducing misses is more valuable than reducing dodges, and both Hit Rating and Expertise rating decrease both at the same rating (16 hit rating = 1% hit, 16 expertise rating = -1% dodged/parried).

Or am I just missing something? So why rate Expertise so high over STR/Haste/AP/Crit?
