I'd find it possibly amusing if you get instagibbed, but thats not up to me to decide.

As for the shields, I see no reason why the Romaioi would have industrially mass-produced identical shields, they are just like every warrior-kulture barbaroi around and near the Hellenes. In fact, not even the civillized hellenes use uniformed pattern shields.
