Yeah that was a real problem with the longbowmen in MTW, but then again even though the longbowmen almost had the rate of fire they should historically have (dont remember how fast they fired) they didnt have the amount of ammo that they should historically have which was about 60-70 arrows or so. You cant have one without the other.
I its opinion that they just went from one ekstreme to another (so to speak).

But i think that the biggest problem is that theres no difference in different crossbowmens rate of fire (you up the dmg and range, at no expense!)
I still believe that either CA or perhaps, even better, a modder should do something about this.
