I was thinking about starting a Dong Zhuo campaign, I like having a challenge. However, I hesitate since Dong Zhuo starts with the Han Empire as a vassal and given how the game works right now I get penalized (I become untrustworthy or worse) if a faction breaks an agreement with me by attacking the Han Empire, which is likely going to happen. Given this is it worthwhile to sign trade agreements etc. with any faction except the Han Empire when one plays Dong Zhuo?
I was recently playing a Cao Cao campaign and ended up with a lot of problems after I had become treacherous due to a faction's attack on one of my vassals. I would like to utilize diplomacy in addition to brute force to win.
