Mhm, i can see no difference when i use vital spot (target -43 parry) and hawk (+17 attack rating) vs. none of them.
I think -43 parry AND +17 AR should make a recognicable difference?

At a certain point, any extra AR or parry resistance will be completely negated. If you're doing 1100-3000 damage listed, you are incapable of doing more than 3000 damage, even if you had -430 parry and +1700 AR. It's possible that your AR vs their PR is stacked well enough in your favor, that you can't see any difference. If it won't kill you, try taking a few shots on a dark orange/barely red mob with and without.
Alternatively, vital spot just isn't implemented ;p
