I understand weapons and the like need rebalancing at the moment, but I've got a suggestion as to how these weapons should work.
For starters, edge weapons should still rely slightly on their weight, especially if wielded two handed. An extremely sharp dagger is on par with a greatsword for cutting flesh, but not armor - perhaps the weight of a weapon should add to armor penetration?
Secondly, keeping with the idea of 'armor penetration', edged weapons should be more effective against flesh, whereas heavy weapons should batter through armor with ease. A knife is better at cutting meat than a maul, but a knife isn't so useful against meat in a breastplate.
Thirdly, weapons should be able to be dual wielded. I like to organise my dwarves into individual types - for example, footsoldiers are there to take the majority of beatings, and should be very tough and outfitted with heavy armor and shields. Berserkers, however, are my more agile dwarves, armed with their axes, leather armor and superior speed, and are meant to keep just out of harm's reach as they dole out punishment. You can guess that they take a mashing if they aren't skilled enough. But that being said - what is a berserker with only one axe? Naked. They should be able to wield two.
Also, the native dwarven weapons should be expanded. We have axes, swords, crossbows, hammers, maces and the like, but how about things such as mauls, which are big two handed hammers, two handed axes, greatswords, morningstars, and other hefty weapons and the like? I understand that the game has already got greatswords and greataxes, but these are too big to be handled by dwarves. Wouldn't the dwarves simply forge their own two-handed weapons? After all, you can probably get more strength into a sword swing if you use both hands.
Am I being followed here? Good.
Next, why do artefact weapons always follow the basic ideas for weaponry, and the dwarves aren't being creative? 'Artefact' weapons could be randomised to a point, for example a large axe with a spear-point on the top, so it can be used to skewer the enemy and hack their arms off?
And, finally, can shields have an impact on the wielder's accuracy with their weapons? I don't know about you, but if I had a huge tonne of steel strapped to one arm, i'd feel a bit more off balance when swinging a weapon. Perhaps this penalty could be mitigated as the user's aptitude with shields increases?
