So I've come back to the game after several years (last played during sword of islam), and I'm wondering what the general trajectory of the Abbasids is at the Old God start date- will they just keep blobbing or will decadence eventually take them down? I've been playing a Karen game, and I'm trying to decide if I can keep nibbling around the edges and waiting them out, or if I need to start finding more direct ways to undermine them.
