i see now what you meant although personally i consider getting hit as getting hit, regardless of worn armor... however what you describe (direct hit past armor, weapons, shield) could make for a good rationale behind critical strikes!
EDIT: what you said about soul caliber made me consider another possibility worth looking into... counter-attacks (tagged with the parry attack or as an inate skill? intresting to ponder or consider <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" /> )! or perhaps a parried attack would carry a stamina loss or stun effect for the attacker? the possibilities are endless...
