i messed up like you did, but the problem is not the weapons. the real mess up is the ship.

i got the star cruiser because i liked the way it looked. the ship is a dud. i even upgraded to the fleet version and still no help.

i tried every set, weapon type, console layout, etc. and the star cruiser was always my weakest ship.

i fixed the problem though. i went in and stripped the ship and discharged it. problem solved.
