My personal view is that people should stick to their ships. I was dead-set against the LWB using anything but the Civilian line, but everyone else kept hammering me until I just gave up on it. To me, every LWB should be in a Griffin, Eagle, or Roc.
The same goes for the GC, Unioners, Gaians, and Xenos. If the NPCs fly the Civilian line, I think the player factions should, too. Quite honestly, even though I have the RP that my GC used to be a BD, I traded it in for an Eagle recently because of this conviction. I'd hope you guys would use the Civilian line for the same reasons, but I see that you'd rather keep the BD line. Whatever floats your boat, but you lose some respect from me for it, no matter what 'deals' you made...
