A better Centurion than Centurion in the release it debuted. Back then, Centurion had terrible turret arcs, and skills were strong enough that Warfarer could be a decent frigate-sized warship (it could aim three guns at a target, while that was nearly impossible for Centurion), basically a frigate-sized Mule. Centurion back then was a shuttle with better shields, worse than the likes of Lasher or Wolf.
Today, Warfarer is awful for combat and outclassed by Shepherd as a frigate-sized freighter (thanks to Converted Bay hullmod adding +50 to Shepherd's cargo). It is the first ship to die in combat when I take Apogee start. Even Shepherd is a better combat ship - and freighter - than Wayfarer.
P.S. Warfarer was also Cerberus mark II. Cerberus was an attempt to make a combat freighter, but it was too vulnerable like the Hound, so Warfarer was the next attempt. It worked at first, but now Warfarer is bad, probably worse than Cerberus because at least Cerberus can flee with Burn Drive, but Warfarer cannot.
