Personally I believe:
(1) the federated suns is not a staff favorite
(2) the current fate of the federated suns has nothing to do with #1. Despite my frequent disagreement with their decisions, I believe TPTB are professional enough to keep from extinguishing a faction simply because of personal bias.
(3) the current state of the federated suns is a good thing because it means a chance to fight, and that we're rid of caleb (as well as fairweather fans who only liked the suns because the outlook was, well, sunny.) It will also give us something to point to, to people who still believe that because the federated suns did well in the 4th succession war, pulled out a draw in the war of 39, and then bludgeoned itsself silly in time for the jihad, that the suns are "always winning."
(4) I'm pretty sure the similarities between the Federated Suns now, and the Federated Suns in the first succession war are intentional. The Suns may have drank deep of stone's kool-aid, but if they do not kill us now, and bury the head seperate from the body, that we will rise up and strike back so hard that clan ghost bear will have to deliver us a "Welcome to the neighborhood" basket.
My opinion of the art in the book varies, but its mostly a matter of personal aesthetic preferences. the art is well executed, I just dont like the way a lot of dark age mechs were depicted to begin with. My opinion of the unit stats varies as well (I dont have much use for Stealth Armor, but I'm really liking the destrier/ballista, and I like the AS7-D2 variant a lot.)
