I will do an auxillia revamp at some point but not sure when.
I did not think that there would be too much difference between Augustinian Legionaries and Ceasarian ones since this is but a matter of a few decades and except for the introduction of segmented armour, there wasn't any great revamp ala marius reform by Augustus' era.
Go ahead and post some pics for everyon to study. :
Attached a pic of resent skin adjustments for Ceasarian Legionaries. Perhaps it's better to call them Augustinian Legionaries instead.
