No. Because if you keep making the strong weaker, the overall strength of performance will dwindle. Also, 50/50 are not vortex. A vortex is a situation where you are forced to constantly guess between options and keep taking damage until you guess right. If you guess right, the balanced situation would be the opponent taking a massive faceplant but unfortunately that is not always the case.
Picture this... You are in the corner vs raiden. You get knock down he does a low canceled into that EX move where he looks like he explodes. If you got up with a wake up you get comboed . IF you get up you may get comboed if you blocked wrong if you block right he is back to neutral and has a 6 frame move that start his pressure so you are more or less at a disadvantage. If you delay wake up, he doesn't use the meter and can mix you up safely with a low , over head into OS or grab.
The only way i see buffing everyone else to fight this effectively is giving many of them super armor at least on wake up... Or you could just give him some slight nerfs instead of having to change 23 characters in the cases ....
