You need perfect accuracy and speed to slice specific gaps in the armor like necks and armpits). With a mace or hammer, the full blow from it will cause a lot of blunt impact damage regardless of armor and serves to knock people off balance. Try to pound a nail with a knife.
Tauren use blunt objects like totems and two-handers as their primary weapons as well because a 900 lb. bull slamming on top of you with the upper arm strength of a silverback gorilla is going to hurt way, way worse than a sword slicing into you.
