I haven't looked to see if the mace expertise is modifying anything other than dmg, but i also use maces and they are far better than the sword class, although as you mentioned, there aren't many impressive maces i have found so far. i still have my bat of striking with 2 to mana drain and 2 to fire dmg and yes, i am almost always over 80 for dmg. thing is, i have no way of knowing how good or bad that is..i have found some formidable weapons, but they never do as well as my bat with the very low recuperation time and relatively good dmg. it's nice that i have found an effective niche for my one hand/shield (which, btw- the shield is the reason i chose mace, that and the +90% dmg addition) combo, but what if i don't find anything else that's mace class and neat?
