Smite + zeal can get a slight advantage in some particular melee matchups.
But saving 40 pts from zeal/sac can help build a smiter that will be much more polyvalent vs casters.
Either going for foh (which is very nice even with low dmg to trigger fhr once smite was applied) or pts in single res auras (passive max res) or even 20 in defiance for 300% defense boost.
