That's pretty much a warhammer's point- just use brute force to break the bones underneath the armor, basically ignoring the armor this way
Not to mention an axe... is just a very sharp wedge attached to a long pole for leverage.
I like warhammers for their obscene damage, but carry great swords most frequently because of the kill animations. Nothing like seeing a helpless wizard impaled on the end of a sword, then flung off like a piece of wet garbage.
