I stopped my bowsmith and demolished one a few day ago as my remaining 18 archers never seem to do anything. After a disastrous attack yesterday I lost 35 recruits and all 18 archers. Starting up my bowsmith again I quickly ran out of logs for my coking plant, so put it on hold again.
But I'm now thinking, are they worth all the resources, yesterday when they got wiped out was the only time they fired a shot, but didn't actually achieve much.
