AI needs to think faster so combat isn't painfully slow. It makes missing more annoying when you have to wait for your turn watching a screen where nothing happens.
Misses need more exciting animations like blocks and armor deflections. To accurately reflect the concept of armor in D&D, in that it soaks all or nothing. Which is ok because also HP are an abstraction.
Once those two haven been taken care of, I don't think the actual amount of misses is any kind of problem.
