As we can see, he has a good grip of military affairs and common sense and self-consistency. He's no KJA. However, he is unfortunately a horrible sufferer of EU minimalism. Just read his bit on Coruscant having oceans (which we now know must be very small or mostly covered by city themselves).
Michael P. Kube-McDowell wrote:So consider the image of Coruscant as a planet-sized city a bit of Imperial propaganda. Instead, picture a planet with two continents, a major and a minor; the major continent is dominated by an admittedly grand and impressive Imperial City, but it also has the Manari Mountains, a western coastline that's something like Miami Beach in its prime, and frigid northern latitudes which are largely uninhabited. The minor continent is much more sparsely populated--the largest population centers having perhaps no more than a million inhabitants.
