The setups should be banned if TN does not fix the hit status of his attacks once he gets to your back. This is not necessarily an infinite because you can get out of it, at least I can. The OP says you can't get out of it, however, I can and I am losing 50%+ in the process of doing it but new found ways of him getting back there easily he only needs to get back there once to end a fight. When you add this into everything else that he is doing then you have a character that is borderline broken.
@SweetRevenge117 You had help, bum! If not for me showing you something you wouldn't have even came across this. Since it's out in the open and most players will be doing it until TN fixes it (hopefully). I can show you how to get back there freely. Let me know when you are back on and I show you some more stuff, and I'd like to play.
I will say also add that is if this is not handle then I will temporarily be a Gen Fu player and as Lopedo said, it will be " The Gen Fu Classics" come October.
