I get where you're coming from, but the reason I suggest short-chain flails is because it could be functionally similar to the bludgeons already in game. That is, it can use the same animations without any bad side-effects. A short-chain flail would still be devastating, much more so than a regular mace, to the point that using anything with a longer chain would be overkill for most enemies we've already seen in game. And it could still work against shields if you're skilled with the flail, or lucky. But, we want to go all out right? Hell yeah I want some crazy room-clearing homicidal wrecking ball on a two handed shaft. But that would require new techniques, new animations etc.
