Persia reborn (or something)

[Hegix]

Just out of curiosity, are there any reasons for the difference in extent between the Parthian and Armenian Persian "Homelands"?

Armenian Persia extends to include both Tarsos, Antioch and Damascus in the west and up to Baktria in the east while Pahlavan Persia draws the line for reforms earlier. I could guess that there is no real reason for it other than they are 2 different devs, but I ask anyway

A bit of praise at the end as well. Thank you very much for adding another dimension to these factions that have quickly become my favorites, just because of the added reason for conquest other than just expansion.
