I just had the Shakturi show up around the rift, and then blitz off for the far corners of the galaxy. I could roll it a bit back and get a fleet or two there, but they're a good deal beyond my current tech level, so I'm not sure if it would have much impact. SO, the crazy idea is, put a mining base attached to every stinking rock around that rift. Sure, individually they're not that tough, but that adds up to a LOT of gun platforms. What I don't know is if their ships are immune/immortal to attacks when they spawn - the data they do display makes that look possible. There's not much point in investing years and an enormous pile of credit for no purpose.
So the magic question is, is there any point in trying to attack the Shakturi fleet at spawn? Other than to just piss them off of course.
