This game already don't have players. Nerfing things around because you think you're a God of balance would make the things even worse. It's nothing personal, Haste. Just take it as "constructive criticism". I am sure you worked hard for this mod but some changes are not justified to be honest. You keep saying barge would break the economy... What's the point with the economy? What if some players fly barges for making credits? What if the barge is better than a 5ker? Just give them the opportunity to be. There is no "broken economy". Players would make insane money, so what? I don't see what's wrong with that. Barge was perfect before. There are players leaving or give up flying some kind of ships because they getting nerfed (see battleships, battlecruisers, gunboats...)
I'd say asking community for future changes would be great. And by "community" I mean the players who actually play the game everyday
