Have been wondering whether there will be a recruitment system simlar to that of Europa Barbororum and RTR VII (my favorite mod, ever). Specifically thinking about the area of recruitment system - being able to recruit iberian soldiers from your colonies in iberia, for example, and not being able to recruit your elite roops overseas. Especially now, when Carthage is a main faction, because they relied mostly on colonial troops. Most famously Hannibal, 80% of his troops being colonial troops (iberians and numidians) or mercenaries (celts, ligurians and italians).
I think CA should draw some inspiration from EB and RTR VII concerning AOR and unit design, saves them them a lot of work actually. Loved the detail that went into each unit type in RTR VII, would love to see some of those thorougly researched units in RTW II.
