the developers mentioned that ranged weapons (Crossbows, Bows, Throwing Knife, Shuriken, Rocks, Throwing Axes, etc..) automatically hit (provided that the target and the projectile meet on the same tile)... I think this has to be with the limited amount of ammunition. but anyways. since ranged weapons are auto-hit. most people go with Strength, as it gives bonuses for BOTH melee and ranged damage.
This is the info, do with it what you want
