Interesting idea, would definitely make things different.

The current range limit of 10 km is only part of the situation.

DHC's experience a dropoff in DPS after 2 km from target, and beams from 4km

10 km is not just the maximum targetable range, but also the point at which you may as well be

shooting blanks.

If you get an increase in range, I'd be looking for an increase in speed, to be able to close to optimum DPS range in shorter time.
