We will look at emperor faction. Yellow Turbans were buffed a lot already, but issue is that they start with like 20 enemies and AI cant really handle this.

Thanks for reply, according to my experience, reduce the emperor faction economy may help in this case, because they can't spam too much armies

I'm playing with the upkeep +80% and there is still like 6 armies against me in many directions while Zhang Jiao is the last remaining leader of YT. There is clearly a big problem in the balance as it's almost impossible to win because of the lack of strength :/ Even if I conquered almost all the north, the south has too many armies going everywhere around me. Did you have any ideas to improve this thing? Maybe by helping the other leader to survive around the map? It would clearly prevent the fact of being surrounded by every Han Factions.. Thanks :)
