If I were re-releasing freespace 2, I'd make trebuchets bomb targetable. They're fast enough that a barrage would make it through, but the capital ships should have a fighting chance angainst some guy in an Aries at 5k lobbing in trebs 1 at a time.
Maxims do too much subsystem damage for their range I think. Either cap ships should have gotten subsystem shielding, maxims should do less damage, should be ballistic to avoid abuse.Or cap ships should get 3km weapons to shoot back with. I think on hard difficulty though, maxims become more feasable because it's hard to keep them fed with energy without sacrificing speed or shields, making them a liability, which they should be with the damage they do. On easy though, maxims are cheese.
Do tag missles ever do anything useful besides make for a mission objective?
