Hi there. Thank you for the feedback. AI is always an issue and most likely, it always will be. Creating AI players that are perfectly balanced is far from any kind of easy task. We're always working to improve their behavior. You're more than welcome to provide video showing the issues you're facing. I'll relay them to the team. Especially, when you say you can't stick lift, poke, or check. Personally, I haven't seen these stop working on Superstar so if that's happening for you, we need to see it.
It would also be good to see the line change issue you're mentioning. If you get any videos of these, please publish them through your console or put them up on a site like YouTube where they can be streamed.
