Once again, it's not discreditable to say that you are an utter failure in terms of combat roleplay. Your gear is balanced for what it's meant to do;
Asco performs pretty well, go ask the Renegades or any other Freelancer utilizing it;
You have access to a vide variety of guns including Brigand ones, Gallic Civilian and, I guess, Council ones;
Not to mention that whinning about bad bombers when you can use "Eclipse" Very Heavy Bomber makes little sense;
and your Heavy Fighter is okayish.
Of course, when a Brigand faction uses a Battleship and one of the best fighters in the mod to get an upper hand in PvP, it makes life easier for them, but I guess you are doing something really;
really;
really wrong.
I never though I'll have to say that, but maybe you should talk to other players who have no problems with pirate roleplay while using your gear?
