Eklektikos
Eponymous
Plux, I'm hoping we'll get round to that (or the horseman equivalent depending on which, if either, the people decide is the best choice) a little later on. I'm advocating the archers first since they're relatively quick to build and aren't resource-reliant, thus guaranteeing us a fairly effective early strike force. As I say, hopefully we'll be raising a much larger force of horse/swords using the the mass-upgrade method once this early strike force has gone off to war.
