Everyone seems to repeat "warhammers are better than maces" like a mantra.
look, guys, this is only based on arena testing and in arena testing you get dwarfs with average attributes. They are simply too weak to swing maces effectively!
Looking at the raws, one can easily see that maces are in fact better than warhammers! They have twice the contact area and twice the mass, thus meaning the same armor piercing capability but larger wounds.
What arena testing proves is that for average dwarf hammers is better because he can swing it effectively and can't swing the mace.
But who puts average dwarfs to the military and moreso, to be blunt weapon fighters? Even if someone does, what dwarf remains at average strength after two years of military drill?
We should make macehumans or macetrolls figth hammerhumans and hammertrolls in the arena to acquire results more likely to reflect the real effectiveness of the mace in hands of mighty or very strong dwarfs. I haven't done it yet, but i'm sure maces will win as they should.
Back on topic, gold is awesome for blunt weapons and gold mace with that crapton of decorations seems an ideal weapon for your general.
EDIT: i've actually done a quick test with 10Hammertrolls vs 10Macetrolls, all in steel armor (helm, breast, shirt, high boots, greaves gauntlets and shields) and skilled in Dodge, Armor Use, Shield use and corresponding weapon.
Macetrolls have won 4 fights of 4, taking 2-3 troll casualties.
