So I'm looking through the Policy trees and noticed that the Forbidden Palace requires Patronage. They gave it 2 additional delegates, which I guess makes sense because Patronage is probably the best tree for Diplomatic victory, but before BNW I usually just though of the Forbidden Palace as a wonder for wide empires to manage happiness. For me that usually means I'm being more punchy and less diplomatic. And the bonus delegates just seem tacked on IMO.

tl;dr Forbidden Palace being attached to Patronage seems weird.
