Here's just an open question, in the hope that someone can answer me...

What exactly are the Arverni supposed to be able to recruit in Italy? Are there any regional units that they can recruit in Level III/IV government in the starter Romani provinces? Because currently I have an Arverni army stuck in the Roman provinces absolutely incapable of retraining because all I can recruit is Lugoae and Sotaroas, even though I have Rome and an ultra-developed MIC complex. The nearest stop for retraining is a long withdrawal up the peninsula to Bononia, which would mean uncovering southern Italy to an ominously growing Epeirote army at Rhegion/Tarentum, and I am loath to do that, but at the same time I can't pre-empt the Epeirotes because I simply don't have the strength to be confident of victory.
