As in here, we have established that, yes, evidence for diamondwork quilted armour exists, but from limited regions and almost entirely ending in the mid-4th C. BC. Yet you have reconstructed such armour on units from at least a hundred years later and from locations where no trace of such armour has been found, such as Crete. That is not historical, and so the claim to historicity is false.
If Urnamma says that quilted linen armor is found on third century Rhodes, the same type that existed from India through Mesopotamia to Scythia and Anatolia and down to Egypt for two centuries prior, then by god we will use it for some light armed units also. Whether you like it or not. "Limited regions" my ass. You play loose with the details when it suits you just as much as you accuse us and our mod team of doing so.

We don't have evidence that Pontic generals used the older Persian cheires or neck guards either, but we feel more than fine about using them in our reconstruction of the unit. Because we have no quilted armor on Crete in the third century doesn't mean that we aren't going to keep from using it on *one* unit recruited there.
