I just think you'll get much more mileage out of dagger at hero and will be using mace like a utility spec for boneshatter and cranial. Pre-hero, boneshatter is going to completely wreck a lot of foes. Post-hero, it's an add on most (not all, of course) of the time. Pre-hero, cranial is going to be enough to finish things quickly. Post-hero, your arial cranial is not going to be as effective against prepared foes. Drum and backhand are nice, but concealed is nicer most (not all) of the time. Also, I think you'll kill more with whip utilty. There are some fights you won't win without spamming drum and praying (looking at you RBW giant sword specs) but most of the time I think you'll get more mileage out of dagger/whip. Just MHO.
