Playing Ythril, attacking a city.  Multiple Juggernauts and a hero with maul.  For some reason all the archers (the melee units are pretty much toast given that they're in the way) always go for the "Battleborn".  While admittedly the Battleborn have n times x damage, the Juggernauts are by far the more dangerous target.  So the Battleborn soak up the damage and the Juggernauts do the elimination.  The ranged damage units should somehow consider the proximity of their doom when selecting a target.
