Confirmed for me too on my enhancement shaman, retribution paladin and other chars: dodged, parried or miss on targets which shouldnt be able to with abilities thats should not miss(not on mistweaver monks with dematerialize buff), example parry stormstrike from priest, miss stormstrike(and the priest was not night elf, that has 2 % chance to be missed), and this with expertise and hit chance much over their cap.
