I'm not sure why they bothered with Morning Stars as they are just a rarer form of Heavy Mace in their present form. I think they should widen the crit range on them to 19-20 (those traffic cone sized spikes should do something!). Warhammers have their x3 and maces (of both types) are so ubiquitous that they have no fear of not being used at least until you can get something better. I don't think a wider ranged blunt weapon will break anything, especially one that doesn't seem to show up that often.
