Two things.
1.
*Minor faction Fallen Spire ships buffed quite a bit.
WHY? They seem plenty powerful as they are now.
Because people were reporting that the minor faction ships were failing in the final assault.
I'm not talking about the player-controlled ones. I've added a note to that effect in the release notes.
I'll post a summery from my last game tonight or tommorow, I guess it should give you a good example of why the Spire assaults fail so very much.
(This game they only had to clear 2 sets of 1 core-planet + 1 home-planet, and both assaults failed so misserably that I eventually just butted in and finished it myself. Effectivly they try to take on a 400+ massive ship exo-attack "head on" ...
)
I have to check the exact saves but I should be able to give you a savegame where the spire ship are at the point of leaving my terf into AI-terf, allowing you to see how things go from that point on, if you want. (Exo attacks, 400 massive ship strong, are triggered 2min apart .. the Spire-AI cant get in between those attacks without getting wasted.)
You may need to savescum a bit to get around the 10k mk4 Maw waves though, playing on 5.001
Do really like the super DNs though, cant recall they where in my previous game, but I might have missed those still being amazed about the sheer power of a DN
