C'mon guys...really!?!?! a skill that allows you fire more torps? Thats not a skill thing, thats an equipment thing. Its a physical limiotation, not a skill or intellectual limitation when operating the system. Thats like saying BO Lt. Uber Skillz can make his phasers travel faster in vacuum of space as his skills improve. Or Ensign Lamme Modal increases the number of fighters the carrier can hold as his skills increase.
Dont just accept any cheesy and gamey feature just because it follows typical MMO methodology.
Honestly? Not much actual "skill" a tactical officer has in space. He presses a button to lock onto a ship, presses another to fire a weapon. You can't really build from there. Maybe "expert timing" which allows him to fire the weapons at just the right time to hit a system and do the most damage, but that's about it.
