Bah, its hard to explain what I mean but when I say uncommon I mean that typically you would not find such units in an army, it would only be while campaigning outside the homelands, in nearby regions, etc.

I'm actually for gameyness in this instance. The only real difference between Makedonia and Epeiros if we followed through on this would be a few units here and there (Hetairoi, etc.) and the fact that Epeiros gets way more choices than Makedon. I understand your approach Arjos, but I feel we are better off leaving more clear divisions between factions rather than making them more similar.
