Um, internal figureheads are very, very important. They set the tone for the realm. Kas did an excellent job at that for a little while... then he turned into a Glaumring-clone.
So is diplomacy. I see extreme failures on Terran's part. They did great getting the north to join, but beyond that its been downhill. Sure you have convinced then to suicide their army south, but there are a lot of other things they could do, that actually help, especially now. Also, I see your point on ruler's setting the mood, but that doesn't mean they should do nothing but help out realm morale.
