I'd like to see some weapons' system work like the Battlestar Galactica' flak. Say what you want about the series', but the weapons are very well done. Basically, the shells are high explosives filled with shrapnel, exploding in 'Airburst' patterns, very much like the tip of a watergun.
The fields of explosions you see over the Battlestar are just 'flak-fields', impossible for fighters, missiles or other to pass through.
So what I'd like to see, would be that capships have rows of the weapons, activating them when hostile objects comes to a ~1500m range. The weapon would have an effect at some ~500m from the hull. The ship proceeds to just shoot wildly towards the enemies, making an impassable field of fire for the hostile to attack through with anything but small missiles and gunfire. As a counter, fighters are forced to shoot out the flak turrets themselves. I assume capship weapons' fire can't damage their own hull or subsystems, so I think it'd be replicated nicely enough.
Could a coder call my bull****, or what do you think?
