Bah forget the stars.. they are only over polished decorations for you'r FM while standing in the battle map. I prefer morale boost many times over than any number of command stars. and i dont like the idea of my FM always standing behind his men blowing his horn from time to time. i ussualy order my FM to flank the enemy, engage the enemies cavalry, charge the enemies infantry(so long as its not heavy infantry or pahalnx) and so on. This way my FM always get traits such as Roman Hero to Legendary Hero(+5 to morale) this way my men are hard as bricks to break and would end-up fighting to the last man rather then run like little girls Lol.

Although i have been wondering why the AI's FM have like 6-10 stars when their trait list only depicts them to have only 4-5 O.o
