When you transferred all the fractions to the new combat system after the seizure of the last land from the rebels and the Goben kingdoms there are no assaults of the capital, for example Erak Cave Troll (Only in Capital)
(300 Battlescore)
Erak Ogre (Only in Capital)
(350 Battlescore), Elite Rebel Guard (Only in Capital)
(175 Battlescore)
Rebel Lord (Only in Capital)
(225 Battlescore).
There are no battles to seize the capital and no battles with these units
