A lot of hard words for someone who has participated to no discussion on the matter before. This is the best way to be ignored here, you know.
Also, there is nothing sacred here : no ability needs to be present just because it was in vanilla. Things are there because one member of the team decided it was better like this, most often after consulting with other members. If you want to discuss the validity of that idea, you can try to ask in a calm manner what were the motivations, and then perharps you'll have an answer, and we can discuss.
You're right, I'm sorry, that was too harsh.
My thoughts are unchanged, though. Why on Earth was the Chu-Ko-Nu changed like this? China's UA rewards you for gaining cities. Why would you take away the one aspect of their kit that facilitates that?
