Those are some scary fleets. That's a lot of boresights to line up, but the enviroment is so target-rich you can't really miss. I tell you one thing, the EA 3rd age list doesn't scare me with my Centauri, but the Warlock sure does. I would not put an Octurion up against a Warlock and expect a win. That is a scary ship.
All I can offer by way of advise for the Centauri at this point, then, is concentrate fire on the scary Warlocks and Omegas a few at a time, kill them and move on. Those beams are your biggest danger, so remove them as soon as you can. Don't be afraid to use APTE to close the range and bring your precise beams to bear, and for the love of the Great Maker, watch his fighters! Raziks and Sentris on CAP, Maximi in close to your capital assets and use primary arms to kill them if there are no better targets. Kill the carriers as soon as you can, take away his fleet carrier trait. Going to be difficult with so many on the table, but do what you can.
This will be a tough battle. Good luck, and get us some photos!
