Radiance and Skarovas.
Radiance seems fairly ancient-y, at least with some modified textures it will. Plus its my favorite Advent ship. And it is long and slender, which fits nicely as ancient races tend to be arrogant dicks. And with its pulse lasers on the sides it makes a real nice escort for Titans, as its got a fairly good forward punch with the beams and plasma batteries and the pulse lasers act as frigate flyswatters. Detonate Antimatter to stop LRF's and Computer Control. Additionally Energy Absorbtion helps with giving it endurance, plus a mini Stellar Converter beam in the form of Cleansing Brilliance.
Just replace Animosity with something that doesn't suck.
The Revelation is the Flying Jalapeno, right? Not my favorite by any means. I would have to go with the Halcyon. it already looks pretty ancient-y as an Advent ship, with its seashell-like ornamentation. Plus Skilled Hangar Anima and that cooldown reducing aura for energy weapons. Telekinetic Push helps with any pesky fighters, and Anima Tempest probably scares the crap out of people with its mass spamming of drones. A Halcyon and a Radiance are one hell of a destructive combination. Mix a few of each with a Titan, and victory has never smelled so close.
Skarovas is a lot like the Skirantra. With some changed textures it will look quite Egyptian just like the Skirantra does as the Set. Will definitely work as a capital destroyer with its heavy armor, shields, and forward wave cannons. Plus capable in groups as a heavy raiding force.
I definitely agree with the Skirantra. Feels like an Ancient ship with its Egyptian textures. The Skirantra model with the new texxes is a great carrier. Except it feels like it has no real oomph to it, like the Osirus, Anubis, and even the Ra does to a certain extent. The Set even has less freaking fighters than the Venator, and its a Titan! Any Titan should have enough firepower to cause its enemies to have wet pants, and the Set just doesn't. I fear a Venator more than a Set, and the Set costs 10,000 creds, 1000 metal, and 1000 crystal. Venator is less in all, builds quicker, takes less supply, has bigger guns, and more fighters.
