With enough force any damage type can defeat any almost armor type (and a weak enough hit can fail to almost any armor type), but it's a matter of degree. Weapon and armor types are signifigant factors, but complex ones.

There are historical accounts, for example, of a battle where the knights' fine chainmail was so well and tightly made, that swords couldn't get through it, and the knights had to be bashed. However, many other examples of chain mail have wide enough rings that they are relatively easy to stab through with a pointed weapon. Bodkin arrows were developed with very narrow heads for penetrating armor, although they make a smaller wound on an unarmored target than a wider arrowhead which probably wouldn't make it through a breastplate. Weapons and armor evolved throughout history to counter each other.

However the details of such things are quite complex, and therefore difficult to model well. There are many exceptions, work-arounds, and details to consider. At the scale and level of abstraction of Dominions, it might be best to leave well enough alone. Judging from the quality of the existing work, though, I imagine Illwinter could do a good job of adding such details, if they felt it was interesting and worth the effort.
