Hey ZombieRus5, first of all I'd like to say that it's incredible that your doing all of this + Blood and Chrome by yourself. A couple of things from a game that I was playing as Nephilim against 6 Hard AIs.
-The Babylon Destroyer on the Nephilim is missing appropriate player colors like the rest of the ships.
-The Ascension Shrine is missing the ability Icon for the culture bombardment.
-The Holy Ships do not have a UI Icon.
-Alien Battleships can spawn in Magnetic Clouds, where you cannot use abilities. I recommend making a script that doesn't
spawn them there, because they just become useless stage pieces.
-Some Militia and Pirate frigates were missing their UI Icons, specifically the Guarda Flak Frigate.
Overall I had a lot of fun with the Nephilim. The abilities on the Capital Ships are insane, in all honesty the Nephilim felt pretty OP. Armageddon has the be the coolest yet creepiest looking Sins ability I have ever seen. I recommend increasing the fleet supply for the Babylon Destroyer to 75. With level 3 Power Surge, a Babylon Destroyer can do as much single target damage as a fully offensively upgraded Starbase. Those are my observations, now on to a Plague game! Oh, and are you going to make custom maps for the SoTF Universe?
