Our general philosophy is that you should want hit and expertise to make your resource-generating attacks hit (paladin example: Crusader Strike) but not to have your active mitigation abilities work (paladin example: Shield of the Righteous). Probably the right call is to have the damage portion of SotR miss but always get the defensive benefit in the way Shield Block always works. This one-size-fits-all strategy might not work for every ability, because Death Strike is just such a different model than Shield of the Righteous, but that's out general philosophy.
