This isn't exactly a trick you know. Its a feature of the game and you are encouraged to use it for some factions like Liu Biao, who can't have too many counties, and Shi Xie, who gets unique faction resource from having his family members as faction leaders

I shall use this in my campaign...

Perfect for useless commanderies indeed

Its just part of the game tho... use it all the time. But anyway glad to see some tw3k content 😄
