Erm, I believe you are basing your opinion on the mainview icon, and not the fighters themselves. I saw this as their firing range is in fact small, at 3000. They also are at a good speed, they are not much faster than the max speed of capital ships/cruisers/frigates. The latter three have the same max speed, what makes them different is their acceleration. Fighters are at, or just under, twice as fast as other ships, which makes sense. For example, the ISD-II has a MGLT/hour rating of 60, while the X-Wing has one of 100.
