I disagree. I do not think Natalis' handling of Kimbolt, while good, shows that he could be a good leader overall. In fact if he carries out his promise to eliminate the evidence against Kimbolt, then well he's an idiot.
Radovid stands a much better chance at forcing the nobles in line, than Natalis, who himself admits that he doesn't know if he can last for a week *in front of Radovid and Henselt* (what an idiot).
Natalis is a poor leader and nothing was shown to prove otherwise, and even he knows it. Furthermore, Radovid with Anais does not mean that Natalis is out of the picture. He'd be a general where he belongs and excels.
