Do you have quad cannons? If you do you can do the quad + cannons and turrets and put out more dps then doing torp + cannons and turrets. This alows you to put more points into other skils becuase your are not haveing to use skills for torp damage as well as useing tac consoles that effect all your weapons. Such as 3x phaser and 1 cannons etc. On my escort carrier I run 1 x quad 3x phaser dhc, 3x phaser turrets and out dpsed my 1 q torp and cannons turret build.
With the extra skill points i gained for not haveing any projectile skills I was able to put more in defense based skills.
