My hero character is an archer, and kills pretty much everything in her path with no trouble. I've sunk nearly all of her skillpoints into bow skills, accuracy and damage in particular. I also spent a few points on converting arrows (but only splitting arrows) and on arrow proficiency - splitting arrows. Those things are MEAN, even in the balanced 1.44 patch.
(It's also better when you find better weapons -- my hero has a shadow bow right now that inflits something like 18-78 shadow damage on top of the piercing damage, which is somewhere in the 20-50 range.)
