Something I said quite a while ago: fast projectile weapons are needed. To compensate insane maneuverability of fighters and lag factor. Not much damage so they'll be pretty useless against something bigger.
A bit off-topic may be, but I would like to see more variety in weapons as regards their effectiveness against various type of ships. EMP torps, fast projectile anti-fighter weapons, things like that... That'll also bring some fun in trying various weapon sets and result in interesting combinations. This can possibly solve problems with balance, but should be done careful at as they can also screw it up big time.
