It would be nice to have more options to the common ones and interact them with the game as a whole. I played several adventurers, and after getting 3 recommendations or selling high an item, you don't have much to do. The hunt of rogue become odd and boring, and I just deleted them after 2-3 months of play.
For me, this Yeomen can be something useful (but only if they do not get too much gold - they should get silver, instead). Something linked with religions can be useful, too, as both, the commons and the religious games need boosts. We could have several changes, as a warrior man-at-arms class, a thief, etc, but we just can't forget that BM is a game for nobles, and the peasants only do the low colors of the acts.
