They should just make the higher level AI less of a cheat and not blocking instantly after using Battle Butt.
Battle Butt itself has no problems as far as I'm concerned and should be left alone.
As you can see in my video the expert AI in the Cerebella daily did not cheat enough to insta block after using Battle Butt, making it effortless to punish her.
I believe this is a problem with the higher AI in general performing actions nearly impossible for the players. While at the same time they do some pretty dumb stuff and try to use close range grab attacks from across the room.
Such as blocking extremely fast or somehow using a blockbuster right away upon tag in even though I've already used a blockbuster before them.
