Well, alot of classes typically use swords and daggers. I feel the thinking here is somewhat limited due to the armoury system.

With you weapon related mentaly your trying to use to justify your logic, you feel that its more likely a bard uses a wand or magical sceptor or cudgel then a bow or a sword? I am unfamiliar with anywhere or any lore where they use the previous, but I can recall many many times I have heard of bards using swords and bows.
