You guys should consider changing up some of the colors for factions on the campaign map. Some factions look way too similar in terms of the hues allotted to their respective territories. For intance, Kart-Hadast and the Boii are indistinguishable as they are both snow white. Although they are dark brown, the Lusitani are almost as dark and black-looking as Makedonia. Baktria and Pergamon are almost the exact same shade of blue, along with the Lugii and the Numidians. The Arevaci and Sabaeans are nearly the same hue of brown. Roughly half the factions are highly distinguishable in terms of color and shade no matter who they end up bordering, such as the Romani, Hayasdan, Parthia, Koinon Hellenon, and the Ptolemaioi. However, if the Romani ever butt heads with Saka Rauka then their borders will be slightly hard to tell apart (same with Saka Rauka and Kimmeros Bosporos). The various factions with different shades of green, the Arverni, Aedui, and Taksashila, seem to be pretty distinguishable, though.
Also, I know it's not historically accurate, but if a Hellenistic faction such as Makedonia, Epeiros, Koinon Hellenon, Ptolemaioi, or Kimmeros Bosporos are able to capture Levantine settlements like Antiocheia or Damaskos and incorporate them into their empires, then shouldn't they eventually be able to recruit the Hellenistic cataphract like the Seleukids? After the year 200 BC or so the likelihood that the Seleukids or even Baktria have not already been conquered destroyed become very slim. It's a shame, because the Hellenistic cataphract can only be recruited by those two factions, and they are easily the most powerful and astounding-looking cavalry unit that any Hellenistic faction can place on the field of battle. Since EB II is all about changing history, if one of the other Hellenistic factions was able to conquer the Near East and territories traditionally held by Seleukeia, why would they not eventually recruit cataphracts as well? Especially when they will most likely have to contend with either Armenia, Parthia, or both. Even the Romans eventually got around to fielding their own cataphracts in the region during the Principate and Dominate periods.
