Oh, and one more thing: The invention of the Arsenal Dwarf position? That was a Crime. A Crime.
Even a dedicated AD will prefer to sleep, eat, drink, party, or just take a week-long break at the most inconvenient of times. On the one hand, I have to train my soldiers with training weapons to avoid training injuries. On the other, I absolutely cannot rely on being able to switch to real weapons in less time than it takes for goblins to appear, move to the fortress, and massacre everyone, and it's because of the AD.
He's supposed to streamline and organize the military, but he impedes it. Toady, there has always been an entity that handles the organization, storage, and assignment of equipment. It's called the friggin' player. And the player is actually pretty well qualified for the task. Dwarves will never be, and you made them that way. Forcing us to go through that bastard AD rather than do it ourselves is not a bug, or a design flaw, but an extended middle finger from you to the player. It's a dick move, no matter what you intended to be.
So, here's my proposal. I will donate $50 for the removal of the Arsenal Dwarf. I will donate $20 additional if he reappears as a tortured soul in Hell (make his fate High Octane Nightmare Fuel and/or And I Must Scream, as explained at tvtropes.org) in future versions, if the previous condition has been met as well. I will donate -$100 (as in, subtract from future donations) for the AD to remain as a required position.
