Well, even if you armor suffer serious damage, bent and dent into you (btw it implified in the game already, since warhammers gurantee to deliver small portion damage to HP), you aren’t left completely naked and extremely vulnerable to dagger and spear stabs, like it works in the game right now.
Maybe warhammers could be more focused on deliver damage trough any armor kinda how they do IRL and not removing armor?
