These seem so basic that they've probably been brought up already, but it's pretty hard to search big forum threads soooo:

A non-stealthy commander can use the Black Heart to assassinate foes from inside a besieged fortress. I don't know whether this unbalances the game, but it certainly contradicts the description of that item, and it doesn't make much sense. How would somebody sneak up on an enemy commander, from the other side of a giant wall, without stealth?

A scout that's defending (rather than hiding) within a besieged fortress seemingly can't be given the order to hide.
