Samus and me performed some tests with nova torpedoes last night...
we found that, depending on the ship, there are certain "vulnerable zones" that take damage when hit...
So, i think there are 2 ways to correct the "dead zones" problem:
1. Increase the explosion range of a torpedo to the lenght of a battleship (so the vulnerable zone will allways recive the shockwave, and get damaged).
2. Making "Transphasic Nova Torpedoes": this means that the torpedo doesn't explode when it hits the hull, but pass through (phase through) the shields and hull to detonate in the center of the ship (or the inside of it) dealing the maximum damage to shields (if those are on line) or hull. (i'm not sure if this can be done)
We also found that torpedoes are too slow to be considered "a threat". A nova torpedo fired from a distance of arround 200-500 meters, takes almost 8-15 seconds to reach their target, let alone firing it from maximum distance..
Torpedoes should be twice as fast. (or at least 90-100 m/sec)
Remember that the torpedo concept on freelancer was designed having in mind that the CapShip (or station) targeted was static. (i dont remember capships moving on the SP campaign, exept walker's cruiser fleet and the Osiris, during the alaska rescue).
