i would like to dual wield an axe MH and a mace Offhand. i like to stand out of the crowd. everyone uses swords and it pisses me off that they go w/ what everyone else uses. if you think about it axe+mace > 2 swords.
some axes even have a spike on top for impaling tagets.
so, axes can impale (if w/ a spike)/slash targets just like a sword. and they should do more dmg but swing a little slower.
maces do blunt dmg which is good for unarmored targets or to knock targets off balance etc. they should do the MOST dmg since they should be the SLOWEST.
IMO having a variety of dmg types is better overall than just SLASH/IMPALE damage. it also looks MUCH kooler and more barbaric.
