It's mostly the question of things like embellishments on the armor - if we have a metal cuirass instead of a linen one, could it have engravings on it? Could the greaves have some decoration? Is the helmet purely smooth, or would some design on it be acceptable? Some low level Hellenic units even have helmet decoration, so is it too strict to say these can't?

We pretty much have agreed to drop any pattern on the cloak and any fancy border on it - that was the big first move.
