Err, sorry about not specifying the faction I was talking about...
Yes, my idea is to eventually give the romans a slightly different AOR choice by allowing them to recruit factional cavarly only in Italy while at the same time getting AOR cavalry from auxiliary barracks everywhere else.
They would get a more limited infantry selection from AOR pre-marius that will be gone post reform as their factional troops looses AOR limitations.
Still have to think in terms of balance, will let you know when I cook something...
