I think daggers would be a lot more interesting and practical if the time it took to unsheath them was reduced considerably. I'm often tempted to switch to a dagger after hitting a guy a couple of times with my main weapon, just to finish him off for style points, but the unsheath time makes doing so really cumbersome. The reduction should not be so great as to grant a "free" attack and switching back to the main weapon should still take time, such that swapping back and forth between two weapons gives no advantage.
Actually, a wider variation of unsheath/unholster speeds amongst weapons of different sizes in general would be interesting. It would make smaller weapons more practical as sidearms, with the side effect of discouraging the crossbow + bigass sword/polearm combo.
What do you guys think? Is this moddable?
