doesn't matter if its ranged or not, hit rating works for both including spells as well.
the problem comes form elsewhere...
my priest spells do not miss either...
any of you having any resistance ?
that armory shows 7 hit rating not 11... and no talents spent in getting more hit.
i guess thats not what you looked like, but for now, like everyone else... i must admit that your problems comes form the fact that you are not hit capped !
EDIT:
wait a second, i just reread your post... you are all rogues ?
if so then you could have also taken a parry as a miss, but parry and doge can happen even if you are hit capped. thus rogues will have easier ways of evading your abilities because of their high dodges. it could have been just that, he dodged or parried.
