Yeah, Arcachon has the exact opposite issue as OW, they have two courtiers and one priest and everyone else is an active combatant. With two warriors recently locked this allows them to get around 31 people into the field, which makes the force a looting machine.
It's also oddly unified, I'm actually suprised Edara didn't move to make Arcachon a vassal state at the start. Right now Arcachon and the Southern Cross look to be winning the war, and I don't see much hope for OW to mount a decent offence, or even a really passable defence.
