Scouts were changed so that they cannot lower loyalty or increase grievance of a city. As your report shows, they can destroy fortifications. This is to stop the defense against scout bombs of simply closing your gates. Now you have to chose between 15-25k archers, and 400+ archer towers... which can be destroyed by a 100k scout bomb. A city still cannot be conquered with just scouts, though... which was the main problem and is thankfully solved.
