I can honestly say I have never been forced to warmonger (post-patch) and again there have been enough AAR's that recount "peaceful" strategies to testify as such. Now if I start a game, with the intention of maintaining peace because I want to spend most of my time developing infrastructure and building an empire, diplomacy is the tool I use to enable me to do so. Thats a heck of a lot more depth than it was before. The same criticism could basically be leveled at cIV except diplomacy in that game went completely the other way - establish a religious bloc, sit back and do nothing. It promoted such a passive form of diplomacy that comparatively you could say that system lacked dynamism and depth.
