This site as you can see on the character page takes into the scoring system:
considering your spec of course.
Unfortunately there is too many classes/spec with "hidden" stats :
- resto druids in tree form
- balance druids in moonkin form
- feral druids in cat and bear form
- shadow priests in shadow form
- DKs with auras
Also there isn't any wow related web site (including armory)where you can see all those "hidden" stats.
