Lafiel I can't find a difference in the code except the area damage either, yet the Photon Torpedo destroys shield generators that it hits the arcs off, the quantum torpedo doesn't. This cannot be down to the fact that the Photon does more damage on hit, as in the code, in case of the shield hit, the Quantum inflicts 10500 damage, the Photon 8000.
This is consistent with the behavior observed in the game, a deflector shield hit with a photon torp takes less damage than with the quantum torp, with the unique difference that the Photon torpedo ALSO damages the generator itself.
I just want to remove the damage to the generator, because it is just too strong.
