If anything I’d like to see the AI try to shatter shields when they have numerical superiority. Because as of right now they tend to avoid shield splitting past a round shield type (unless they are Orcs, but even then it’s a very rare occurence). This should make scenarios like a lone warrior surrounded by half a dozen of zombies with axes more dramatic as shield will break and he’ll be overwhelmed at some point.
They actually already do that, but perhaps not by enough. The likelihood of going for the shield is increased by 1.25^n, with n being the number of allies surrounding the target, i.e. one ally adjacent increases the chance by 25%, two would increase it by 56%, and so on.
