I hate to be the one to bring immersion into this, but I do have to say shooting from over 50 feet is really hard to do accurately, let alone under pressure and the heat of battle. I would like to see range of accurate shots being a stat. The higher the level, the better you are at shooting at a higher range. This would mean a higher range overall, but if you are shooting from too far at low level, you'll be missing often.
The whole shooting below or above thing... it's too susceptible to exploits.
