Good point Gaiten, a 'desperation' which gave birth to the Tetrarchy and to the following developments of the IV and V century which turned the Roman Empire of Octavianus and Marcus Aurelius, into an Eastern Despotic Monarchy. This is IMHO a precise cultural choice, CA is telling us: A)During the second half of the III century there was a serious and deep crisis. B)The Late Empire of the following centuries was built on the basis (ruins?) of this tragic crisis. C)What followed was a radically new building, grown in a political, military and cultural landscape of crisis, war and destruction.
All this is IMHO a good cultural work made by CA, in practice they are telling us they have rejected all the contemporary consolatory explainations concerning the Roman Late Antiquty, consolatory explainations stating that the Roman Crisis ended at the beginning of IV century, that the whole IV century's history is for the great part the history of a 'Rebirth', stating that there were no more problems, that the economy was now flourishing, the army was stronger and better equipped than ever, and that the new Christian Empire refounded and pacificated by Constantine (For this kind of 'pacificated historians' Diocletian was in fact just a 'historical accident', something like a 'quantum singularity', like the Huns, used to explain everything, also the Fall, of course) was the 'natural evolution' of the old Roman Empire.
Now, the new players of this interesting new DLC are experiencing another thesis, maybe less pacificated, but in my opinion also more realistic and accurate.
Now guys, before saying I'm wrong, I'm outdated, I'm excessively tied to the old Gibbon theses and that I've no sources and that contemporary archaeology states that .. bla, bla, bla, .. let me remind you that this is just my personal opinion, based on nothing else than half a century of readings, passion and cultural and political choices and experiences.
