The reason people aren't playing Bespin on PC is because of the awful frame lag when heroes are present. This was introduced with the last patch. Each hero makes it worse, so having 4-8 on sabotage is really, really bad, as in half second pauses over and over. You even notice it in walker assault with just 1-2 heroes.
Bespin performed pretty bad for me pre-patch, now I don't even bother.
As far as servers with clans go, I'm keeping my eye on Galaxy In Turmoil (
https://www.google.com/search?q=galaxy+in+turmoil). If EA/Disney don't shut it down (which seems less and less likely as time goes on), it could be exactly the kind of game we can reboot our community with. It's a remake of what SWBF3 was going to be before it was cancelled, except they are being very careful not to use Disney's intellectual property (no John Williams music, remaking their own sounds, etc).
