Stop panicking.
We don't know how long Slide Head is untechable for. You may still have time to get across the screen while they bounce, especially with the FRC to speed up your recovery and let you go straight into Hammerfall. If the opponent is clear across the screen: you're Potemkin, deal with it. Do another Slide Head. You've got options.
Speaking of options, do you realize the cool shit this new Slide Head could give us? I'm guessing not.
Also, Judge Gauntlet feint. Really, you can't see the usefulness in that? Just having that option will scare off some of the JG punishes. If they run in and mash jabs, cancel and Buster. If they go airborne to avoid it, cancel and Heat. If they clear outta town, cancel and get back to business. It makes JG useful as more than just a hail mary.
Please, remain calm. Let the loketests do their thing.
