Even aside from my 9 Command general, the Captured vice is actually not a bad one to have. There are plenty of ways to get your general a few (3-4) stars to allow his troops a small edge in battle. Once he has a few stars he can start winning battles in his own right.

The global Morale boost is pretty decent for the loss of a single star. I might have to start looking for units with Captured commanders to promote with titles and turn into fully fledged generals.
