my thoughts on it
crossbows are just cool
lets not forget the 1/6 CR kobalds that can easily dish out 1d8 damage (this is the scourge of all the low level characters in my campaign), plus, if you don't like a crossbow, then DON'T use it!
Crossbows can be concealed, especially good for rouges. Bows also have to be strung up (if you DMs are making this a rule

), taking a round to do this, whereas with a crossbow, you can keep it by your bed roll (noise in the bushes, sit up, *TWANG* *THUNK*), whereas with a bow (noise in the bushes, get out of bedroll, pick up bow, string bow, get arrow, knock arrow, shoot arrow)
And, bows aren't always knocked, you keep the arrows in your quiver, so for killing shots, keep a concealed covered hand crossbow with a bolt covered with blakc lotus poison in your bag.
If you really feel the urge to have to change this rule, then change it! although it doesn't really need it.
Someone said it would suck for fighters to use crossbows, well thats why they don't use them

.
For militaries its just more fun to describe, instead of running away, knocking an arrow and shooting, it's a row of people stepping back five ft. (or foward, depending on the situation) and shooting a WHOLE bunch.
In my opinion, crossbows are for non fighting classes to have a fairly good ranged weapon, and to use for flavor, whereas bows are just better.
