wodmarach: The point of the crossbow was that any idiot can use one with 20 minutes training rather than the years it took with a bow
That's not...entirely true. A bit of a historic misconception right there. In that time, giving a peasant a crossbow wasn't making him a killing force, but rather a "fodder" for the enemy's archers. The crossbow was fired at much shorter ranges than the longbow and took much longer to reload, but had a heavier stopping power against armored troops. Tell a guy to pick up a crossbow and hit a moving target at 150 meters. You still need lots of training for that, but firing at point blank targets while hiding in-between your own fighters wasn't rocket science.
For game context, an experienced archer gets a stronger mid-range weapon and can fire it quite effectively from the get-go.
