In every patch of Civ V I have found Declarations of Friendship to be nothing more then an invitation for the AI to ask me to give him free stuff, giving me diplomatic negatives if I refise. Now that DoF's are temporary it seems they carry over the "You didn't give me free stuff!" red mod, but they do not carry over the "We declared friendship.declared friendship with the same people" green mods. So, is there any value to DoF's now? Should I start saying no to all of them?
