I'm sorry if my expectations for the future of this faction sound like wishing ill fortune upon it. However, this is the ilClan's era. Conditions must be so that the ilClan dominates. If TPTB are willing enough to let the FedSuns come out of the hole that they placed the FedSuns in, then sure. I'll be ...content with it. Heck, if the FedSuns can do something equivalent to the Doolittle raids, I'd be over the moon.
I am going to float three ideas, and I'll let you decide how unhinged they are.
1) A lance of Rabid Fox Scarecrows pay a visit to the Death Commando barracks while the Death Commandoes sleep.
2) The grand majority of the Snow Raven's warships receive updates to their navigation software and their next jump places them inside the nearest star.
3) Two Sword of Light regiments are killed to a man trying to hold New Avalon from Julian. No Quarter is asked for. None Given.
1) is a short-story and probably won't do more than feed the anti-Davion loudmouths out there.
2) Uh, why?? CSR isn't the one occupying half the Federated Suns, They're not (really) a factor. (Navies are weak in the setting and will continue to be so.)
3)This one works. This one
makes sense.
I'm going to counter two of these with an alternate proposal, and it links with your third.
Begin with a basic understanding: "We have succeeded to the point of failure", aka Pyhhus said it best: "One more victory like this and we are undone."
The Draconis Combine is grossly overextended, a victim of their own success and the short-sightedness of the Warlords currenly pulling Yori's strings. Caleb's mistakes and stupidity may have made this possible, but they also made it possible for pragmatic, intelligent, junior-in-service-time leadership to take the reins and recognize that there are, in fact, orders you don't follow and lords you don't obey (but there are lords YOU DO obey, and Orders you carry out!)
Palmyra might have swallowed a number of elite units, and cost the Federated Suns most of their heavy Naval, but that's not necessarily a bad thing-it also purged the AFFS of a huge number of connected incompetents.
a Leaner, Meaner, more-fit-mentally AFFS under Julian takes the field in a controlled, intelligent manner, and proceeds to ram the DCMS overextension right up the Warlord's ass sideways.
