AI factions progress in campaign.

[Dyabedes of Aphrodisias]

I never saw the romans invade greece and thats a pity. Once as Karthago I conquered epeirus and greece and gave it to the romans and still they rathertried to move their armies to vindobona and massila protect their belongings in greece and lost everything to 2 makedonian fullstackt in 10 rounds... (7 cities)

I've seen them try in my campaign. Not successfully, but a try nonetheless. They sent a half stack into Epeiros proper, but failed to send any support behind it.
