The AI, 1 v 1, versus the player in battle is really bad once you get the hang of the basics.
What I don't get is why AI never uses kick or shield bash vs the player. If the AI used bash/kick when appropriate, like when the player is spamming shield block, as well as the AI occasionally/randomly tossing in a kick/bash when you get up in their face, I think this would be a game changer.
