Winning by any means is not the point. That is being unsporting.
If your use loopholes and shortcuts to win you are basically cheating and it's either because you HAVE to win all the time or because you know that in a fight with similar load-outs (which is not using fighter weapons) you'd lose.
The RP should dicate your weapon load-outs. All your corsair characters should only have corsair or civilian ships with corsair weapons on them.
The RM do this, I do this, most other people on the server do.
If your characters alignment means you can't buy weapons from a certain faction and you can't get them by looting, tough.
