I think the same case could be made for most other ability scores as well. Strength: you need a heavy draw weight in order to punch through armor. Constitution: you're typically firing multiple times and you need to carefully center and hold your breath. Intelligence: you analyze the speed of the wind, the possible trajectory, the movement pattern of your target. Charisma: umm ... you ask the arrow to pretty please hit the target?
More seriously - I really do think strength or intelligence would also make sense but for the most part I just wanted to make the joke about charisma. I don't see a need for it, I don't think it's a
bad thing.
