Why woudl Aurvandil be weaker? Are they having food problems, too?
D'Haran scout reports from several weeks ago showed regions going rogue/low control. My guess was (and is) that they jacked their taxes up to 25% in order to afford their 30k cs army to smash the 'Moot, and then had their regions go rogue while they were smashing the walls of Paisly.
