I can say he shits on D'Vorah pretty hard from just about every point on screen. She can't win a zoning war unless he just really fucks up bad, so she has to try to slowly work her way in against his zoning. She's useless from outside her f2 range and she doesn't want to be within his b3 range, so really she has to sit right in the danger zone of his db1, which she is utterly unable to punish on block unless the 2nd or 3rd hits whiff. If she can work her way in past his straight skulls, up skulls, and sky corpses, and if he doesn't just frame-trap her with his massive f2, and if she can somehow open him, she can get a max of 19% 1-bar, though usually a 9% string into db4. And then she has to do it again, and again, and again. If she makes a single mistake, she's eating 30%+ and being sent full-screen to do it all again.
She can't risk a non-amplified db4 due to his massive punish game, and she needs to have strepsiptera out to cover her ass, so her entire game-plan has to change to accommodate specific meter-management. She also can't risk contesting her negative frames with d1~db4, as Shang will win all such trades into 30%+, so anytime he blocks her pressure, her turn is over and she has to eat his mixups and frame traps until he makes some sort of mistake she can capitalize on. If he doesn't make a mistake, it's very difficult for her to ever get her turn back.
Due to how new he is, I'll put it at 6/4 Shang, but I could see this easily being an 7/3. It's pretty insane.
