The only time I've seen much of a problem with range is on large open tables with the floating table option......As soon as you add asteroids, or some other means of terrain, things tend to level out quick. Speed is good unless you have a lot of small ships going up against really huge ships armed with many long range guns, because even if the small ships are really fast, they take a huge beating on the approach.
What about having a modifier for speed? Maybe a -1 penalty when targeting a ship moving faster than say... 8 or 10, ect.
Outside of going evasive, smaller ships really don't have much in the way of avoiding fire......
Still, in the end, I haven't seen too many issues with the range costs, as they are now, except in battles with extreme differences in the hull size of the opposing fleets.
Personally, I'd love to have the ability to add heavy ablative armor to a slow ship with shorter range weapons, and just absorb the hits until I can close and hammer. I have an idea for a fleet, and the concept of mid sized heavily armored ships would fit quite well.
