Doesnt happen much in games where your in an army like that against thousands of enemies firing blindly into groups, you normally have your screen centered on your targets. As Tsuyu said, in games crossbows tend to be fast to reload and can fire much faster than regular bows. However in games like Skyrim id prefer the feeling of tracking my foe with arrow tip and feeling the satisfaction of watching that arrow hit them. Rather than firing multiple arrows until they drop down, would just seem more skill involved with a regular bow.
Fair enough, my inner history geek gets the better of me sometimes.
