I, for instance, played the undead chapter a multitude of times, trying to make Duskshroud as strong as possible, to see how hard can the orc chapter get in the final mission. Let me tell you, the differences are huge and the pain was real. With the right items and level ups, Duskshroud is truly unbeatable. You end up trying to "convince" the empire general to attack him instead of you, so you can sneakily pass him and reach the hill-top.
