Quite clearly Kacijon has his own ideas which well need some thinking about before he posts them, flying a OC destroyer into a house system is not very subtle for assassins work.
Get an armoured transport, get a prison liner, get a luxory liner. Just don't use a Destroyer as your bank, it would most likely die easier to bombers anyway.
Most house factions probably won't even let you bring an OC Destroyer into their systems too.
