Well, at it's core I can't help but see the Blackout as a meta-level means of trying to shrink the focus of the universe to set the stage for the original MW Dark Age contrivances. But beyond that I feel like there's a limit to how long you can hold together a star empire the size of the successor states without timely communication, and that realistically if it drags on much longer we would start seeing things fragment, fall apart to the sort of states you saw at the onset of space travel, the sort of smaller states that the FWL is comprised of.
I am dearly hoping that we get a return to Pre-Dark-Age Battletech Normalcy, the fortress down, the HPGs communicating again, the military industrial complex alive and well, with the advent of the ilClan.
