I can't help you, Quintus, sorry, but if you don't mind - I would like to add a question on formations.

There are meant to be pre-loaded formations for AI factions to utilize - as in the Roman Manipular formation - to ensure a slightly more historical feel.

However, out of the several hundreds of battles I have fought against Romans - in only one - two days ago, did I see a manipular formation.

How can one make these work properly? Is there a mod?
