Pirate transports would focus more on wrecking defenseless preys more than protecting themselves, wouldn't it make sense if Pirate Turrets had the most DPS but the worst refire and turn rate ? So we can wreck those miners easier 8-)
Make a second weapon group for half your charon turrets
Start an engagement firing the halved group, then as soon as they've fired, keep holding down the mouse button, and flick to the weapon group containing all of your guns. If you've done it right, your guns should alternate fire and allow for a more steady stream of cannonfire. This can drastically improve your ability to deal damage to moving targets.
