The AI tries to get close and do moves. It may feel like it is not defending at that point. This pretty much means you are always playing shoto characters if you always counter what they are trying to do lol. If we made the game always defend and then punish you, you would never win. For now the Ai has to stay the way it is as we keep making bug fixes. Later on we can try and make it do nothing so it defends more. Please try non shoto characters for more of a challenge :)
