I'm going after that lvl 8 npc city tonight. One question though, if someone could answer from experience it would be great (*hopes darwin has a look*):

He states every 6 minutes the loyalty increases by +2. Now at the end of conquering a city, the last loyalty is dropped by getting the public greavence to 100, which I assume drops loyalty by 1 every 6 minutes (same as tax rate). Now if the city is restoring 2/6mins and loosing 1/6mins, thats still +1 by my books. So how do you drop the last 10 loyalty off the city to conquer it?
