Not to mention that you can get Spornsjarl as a "hero" playing a variant of Jotunheim that doesn't _get_ any stealthy units.  (Or at least this was true in Dom2.)
And - heroes should be _heroic_.  The default ones aren't - some of them you'd rather get a bit of gold instead of the hero, _especially_ since the heroes cost upkeep.  If they aren't heroic, why bother having them?
Thank the Great Pumpkin that Turin seems to be working on a Heroic Commanders again.
