Seems a bit silly to have magic as a "weapon art" for Mace. There's nothing inherently magical about a blunt weapon and it doesn't appear to be anything other than an ordinary mace. I would have made the weapon art more in line with Dark Souls II early-game and focused on its heavy, armour crushing blows.
How am I supposed to play without magic and ranged weapons when I can summon the magic spirit of my mace? It's just not realistic! As funny as it sounds, the realism in the weapons, how you couldn't wave a greataxe around like a rapier, how you can't just swing through walls, how you move slowly in heavy armour, etc, etc is what makes DarkSouls combat special. It just seems to be heading away from its realism roots and this armoured knight is spinning with his massively underpowered scimitar weapon-art like he's wearing no armour at all.
Maybe its just plain lazy and they couldn't be bothered making a special weapon swing for mace so they went with a magic buff? I dunno.
Yeah, they are going a bit to far in the bloodborne direction for combat imo. Having played the stress test though there was a noticeable difference in the few weapons I had available but not as much as in DS obviously.
I always play a quick thief type so it probably won't effect me as much anyway. As a thief type, I'm really glad to see the original backstab returning.
