The A2 Weapons Project

How come all of the stock regular weapons have exactly the same ranges? The damage dealt by each weapon seems to have been randomly decided based upon how cool the ship looked at the time. I found the situation irritating. Yet at the time there was little I could do about it. That time has passed. Before you is the A2 Weapons Project. It addresses my concerns and the flaws and mistakes I found in the weapons odf files. In conjunction with the A2 Physics Project, it diversifies the stock races even more. Each is now different enough so entirely new tactics and strategies are now viable options to the old ones.
Why should an Intrepid-class light cruiser mount bigger guns than an Akira-class heavy cruiser? How come the Romulans do not have their "signature" weapon, the Plasma Torpedo as a regular weapon?
