Which makes perfect sense, I mean it's not like the Roman Empire ever improved how it managed it's holdings
That seems fine, a bit less convoluted then mine. In fact, it makes sense - each level of barracks would signify the overall capability for it to produce units. Thus, at first level, we have the basic infantryman, supplied with that Eras arms and armor. Next step, we have that Eras specialized infantryman, maybe even a ranged unit. Then we have the heavy hitting infantry, followed by the peak of that Eras footmen (whatever it may be).
The only problem is the sudden inability to retrain the old units, but realistically speaking such a logistical feat would have been a bit above Medieval world.
