If one uses it only as a quick and dirty way to compare weapons, it can be useful. But we should keep in mind that it is only one way of comparing the relative strengths of weapons ...

It gives a very useful BASE strength.
To me, Range, Accuracy, Damage Type and others are all special features which "make up for" any deficit in base strength.
These special features all have variable value as tactical, strategic and technological situations vary. As such, they are not fit to be included in the base rating.
