The shields have always been bad on a BS, which is why most people fit an Armour upgrade as soon as they can.
The real problem with BS's is the Nova Torpedo, it does far too much damage.
It's damage rating is the highest I've seen in any mod so far, it's explosion range is the biggest too, in fact I wouldn't be surprised if it turned out the Nova was a NUKE where ever Igiss found it (unless it's custom then I'm really confused as to why we've got it).
Another thing I've noticed is that practically every newbie on the server asks "where can I get the Nova?" and then "how much is it?" so right from when they get on the server they start looking for the Nova, because it's the most powerful which seems to mean it's the best.
no-one seems to realise that if the player looting option is turned on and your only left with MOUNTED equipment (like the evovled mod) you lose all Bots/batts and all AMMO too.
Now I don't know about the players who've got millions on they're fighter characters but to me losing over $1 million just because you filled you Nova ammo to full and then got blasted before you got to fire any seems like a really stupid way to lose cash fast.
If that happens 3 or 4 times during one fight/battle/event then someone is gonna end up broke and unable to even get repairs, let alone bots/batts etc.
If you use just sunslayers (using the sidewinder is crazy, because you have to get so close to actually hit the BS you'll stand a good chance of being blasted before you get to shoot the torpedo) the BS hit points are pretty much ok, until the codename weapons start getting used.
Nomad weapons don't need to be altered because they're ALIEN weapons, the nomad have had alot of time to get some decent weapons.
So my suggestions are:-
Lower the codenames to the original stats,
Remove the Nova Torpedo,
Increase the BS shield,
Make it alot harder to get nomad weapons (to count that fact that they're so good).
