Haha, man ever since i saw that you can do an unblockable freeze like that, i was wondering if you could do any unblockable setups after an ice ball. I guess that answers my question.
What could they do to eliminate it though? If they didn't want to change the unblockable, they would have to change the properties of ice ball. They could theoretically make it so that after an freeze attack, if the player doesn't attack them and let them come out of freeze, they could just make it so they knocked down + tech roll.
The tech roll will avoid any unblockable setups after they have been knocked down and are getting up. That's a point actually; are there any good unblockable setups after a knockdown combo in this game? Say like after a combo in the corner. I don't think that would work since they get up quite quick after slide but you get the idea.
