You have a point. However, your statement was still false. Thus my suggestion that later upgrades have anti-fighter torpedoes.
The statement where torpedoes were used against the fighters? True, i say. "If it hurts, it works." But I like the upgrade idea, too.
We have to balance canon against gameplay. In this case, gameplay should override, becuase allowing proton torpedoes to target fighters will neutralize the anti-capital potential of the ships with them. The upgrade is somthing of a compromise. However, it should only apply to X-wings and E-wings. Then again, if you want to, you could make your own mod where proton torpedoes can target fighters.
I don't see how it would waste anti-capital potential. The reload time is fairley short as it is.
Why does eveyone hear use good grammar? It's almost unique in the internet world of forums...
Yes, but they will shoot off the torpedoes as soon as possible. This is almost certainly on fighters, so the ships will waste them.
