His palm strike is still a ridiculous move. Its way too safe and now with this update, its literally impossible to deal with. Even before the update you were lucky if you guessed right on dodging one, but even then, they can still follow up with another attack, or just not do anything at all. You cant even guard break them after. It also breaks every guard break attempt if timed correctly. Its almost like you can just hold down on your stick and when your opponent does anything you press x or whatever and it negates it. Not to mention the follow up light does more damage than a regular follow up light, which are way too fast imo. You can cancel a dodge attack and instantly palm strike.
Palm has always been able to stuff GB attempts if they throw a heavy after whiff. The easier punish is if you have a dodge attack. That being said it's recovery isn't strong and the heavy after is punishable if you dodged the palm. So heros without dodge attacks can punish it. Palm mix ups are really not great.
