It would sell the game just with that, the majority of gamers love bows / crossbows just for the sheer fun of it and it looks cool while doing it;). If it's ever considered by Bungie i would be highly appreciated as I do miss playing games with bows but I enjoy playing destiny why not bring the two together? :D
I had a thought of an automatic crossbow like off the film / movie 'Van Helsing' :)
