I do have to say... this AI patch for Wario brings to light a lot of his balance issues. Don't get me wrong, the AI patch is decent. It's just that it shows how broken Warner's Wario is.

Although, I notice a few things that are annoying, and also perhaps need improvement.

I feel he does a bit too much state reading. Which can lead to some annoyances without exploiting him. Like his Anti Air. He does it almost EVERY time you do a jump in attack.

He does that frame perfect super usage thing.

And finally, he does the guard walk bug.

Now, here are some ways you could improve him. The combos you have for him are pretty limited.... However, he can do a LOT of things out of his aerials. If you watch my videos where I use a balance edited version I did. You can see he has plenty of combos. (And these combos in my edited version work for Warner's original. Save for maybe a few hits from crouching L.P.)

So... I feel like you should tone the difficulty down a bit. But give him more variety.
