I don't think that the BS shields/weapons should be changed.
Pretty much each time I dueled Virus in his Cruiser, me in a VHF, I took his shields down then he killed me. Maybe he's just good, maybe I suck, maybe my ship sucks. Not to say Virus isn't good, but I don't think those above reasons are the true ones. Let's think about this. The Nova torp has an explosion range of 200 meters - unless i'm quite mistaken, that's just about as big as the average BS. Maybe bigger, maybe a little smaller, I'm just going off memory for BS size. Don't you think that a torpedo with that huge of an explosion should do extremely decent damage, even to shields? It's as big as their ship. That's why if anything, Nova torps should be increased in damage, not decreased. I understand balance however, which is why I think they just shouldn't be changed.
Let's face it, BS's ARE jsut big targets. It's no terror. That's just the way it should be given what they are. If you want them to take 10 fighters to take down, you'd have to make them a LOT bigger. And a LOT more expensive. As it is, the Lib Dreadnaught isn't a whole lot bigger than a VHF. Sure, several times, but in the vastness of space, that's not a lot. Someone said "in reality" or something like that they are terrors, and that's just not true. Even in the Freelancer SP, which is just about as "reality" freelancer as you get, a couple fighters bearing torps took one down without even getting damaged. It didn't have time to retaliate before it was dead. That was a Rheinland BS, too, which is bretty darn big. Maybe y'all think of, for instance, a Star Destroyer when you think of BS. A single one-man pilot has no chance at all taking one alone, right? Y'know why? Star Destroyers are over a mile long, bristling hundreds on turbolasers. That's why. The so-called Battleships of Freelancer don't compare at all.
Sorry if that sounded like a rant or if I sounded condescending.
