What I wish is that I could get all the mech chassis goodness of the Heavy Metal DLC, but NONE of the cheese weapons. I tried using a mode to make the system stores and salvage only contain stuff from the original game, but it is obviously not working: I found several UAC/5++ (essentially clan weight UACs, as mentioned previously) and it has made my Glitch in my Rifleman a monster.
I think the campaign plays better with the Mad Max Periphery vibe. I don't mind the cheesy weapons in the Careers, because you often end up facing 8-12 enemies with your single lance. In the Campaign, I'd rather be super excited to find that AC/10++ than looking at ER Medium Laser++ that doe 35 damage for only 25 heat at Large Laser range. It just gets ridiculous so fast!
