How are faction attitudes? Do the Seleukids and Ptolemaioi stay at war with each other if you are playing as Baktria or Armenia or Carthage? Right now this issue is why I've practically stopped playing my Baktrian campaign. Even on medium i'm slogging through stack after stack of Seleukid elites and the Ptolemaioi aren't at war with anyone.

I would probably finish AS off, but I don't want to share a border with anyone in Anatolia for fear of going to war with another faction.
