A cap ship should be able to insta-kill a fighter.
However, this would make cap ships stronger, which would require re-balancing every ship in the game in the end.
That's a lot of work to do....for free.
Just do what I do, and fly a bomber. Either you instakill ur opponent, or you die fairly quickly. At least that's how it works for me, but then again, I suck....so.:unsure:
