I'd see bow as a cowards weapon who doesn't want to take part in melee. Using it wouldn't bring you to fight if the enemy would be fighting, but it would aggravate enemy that is idle. Also, the bow would be useless if the archer would be engaged in melee combat. Basically, something to deal damage with to a person in same room, yet being a ranged weapon. Bit different than circle idea, but I think this is more realistic.
