Yeah thats true, but i think thats because the Greek cities already can build them from city barracks. Maybe move them to urban barracks and add thureophoroi to city barracks? I do think they will eventually need Amoured hoplites against enemies like Rome. So this way in city barracks they can recruit armies with hoplites and thureophoroi. Later they can aditionally recruit armoured hoplites and thorakitai. The thureophoroi should only be available to Greek cities though imo.
and what about the unit suggestions?
