Rome vs Han essay- want get some opinions

[Dan Howard]

It was actually an arms race. Weapons improved, than armor improved, then weapons improved, then armor improved. Weapons were never completely effective against armor, nor were armor completely effective against weapons. But sometimes the spectrum tends to lean more on one side than the other.

This so-called "arms race" has been greatly exaggerated. Of course it was a factor but IMO not the decisive one. This thread about the development of plate covers some factors relevant to Europe. Economic and social factors are the main driving forces for change.
