I have been asked many many many times to give help building a proper Atrox. So I have done a video showing my entire Atrox Build which dishes out some terrifying damage and still tanks like a super fortress. It can heal its friends, heal itself, and utterly murder enemies.
Also, it is not the most expensive build out there by any stretch. I am not using fleet weapons, just Rep gear, not using any Lobi gear, the only piece of pricy gear is one embassy console.
