There is an real example of japanese archers. They shoot incredibely precise but slow. Its more like ritual art shooting. So, maby a good disadvantage could be more AP consumed. Everything else might stay as it is.
Are you mad? Already you get 95% accuracy for 3AP with a crossbow of your own level. Take away 10 or 20 or 30 for some other level? It already happens.
What do you want? 150% accuracy and then go and have a cup of tea for a couple of rounds?
