You reminded me, I wonder if it is possible to change the AOR system into something more flexible and creative. If I build a large enough colony of Macedonians in Carthage, which must be vastly expensive and disliked by the local natives of course, why should I not be able to recruit some decent Macedonian troops there? Alexander did the same thing in Syria and Mesopotamia after all, and just 50 years after his death when EB started, we can recruit even Hetairoi in both of them. Considering that EB-era covered nearly 3 centuries, I believe it's only logical that we got the opportunity to re-write history a little as well.
