Absolutely. When I was younger I would have been all about Bard and I would want him to have 6 shots per turn all with a 1+ to hit because he killed Smaug. But, looking at it realistically, there isn't anything else to go on other than pride in a hero, knowledge that he likely is a good shot with a bow.
Looking at the film though, we are set up. If you had a bow weapon an a single arrow that fits it and you saw bard the Boatman (not yet the bowmen) and Legolas who can shoot 8 targets with 3 arrows while barrel riding down a mounting, which of those two would you have make the shot?
So should Bard have an awesome Bowmen profile and negate his fighing a bit? I think a special rule like Duinhir with wounds vrs monsters is a better suited rule. As I think Legolas can shoot fast and accurate, I think Bard can shoot very accurate (uncanny even) but takes his time and goes for the kill shot.
From what I can tell, there is not much need for bowmen in laketown of the film. So maybe he kept his skills up by shooting fish in a barrel. In the cartoon and in my imagination as a kid, I pictured bard as more a hunter character or woodsmen, and in this film I don't feel that. So again, I think the fighter profile is going to be of more use going forward to the battles. If we ever get a smaug an if there is a scenario for him,then maybe there will be a kill shot rule that any archer can do that involves dice... the only problem with rules like that is you have to make smaug defeatable by forces that don't have bard (like hobbits throwing stones) and you have to have a reason for any Bard rules for use when Bard is not fighting Smaug. so walking the fence, what would you do?
