Thus far, one difficulty with Ermor I've had already that was never a factor in Dom I is a lack of leaders. They still generate undead troops in provinces of their own dominion (in Ashen Empire and Soul Gate), but there are no handy spontaneous Mound Kings to ferry them around.

One improvement is that the Longdead Velites carry, and use, javelins. Javelins in Dom II seem generally improved to me, and this makes Ermor more interesting, tactically, than they were before.
