So after labbing the shit out of this and discussing it with various people I've decided to make a video showing batman's "new" vortex that he can use following the j2 nerf that is actually arguably better than his old one.
Using the combo I used started the video with, you can essentially kill with two guesses midscreen as long as you have a bat loaded before the first combo. Even if you can't get the second bat loaded, you're still guaranteed to take 70% if you guess right the first time.
The best part of this is that the mix is completely unescapable, you can not super or backdash out, so you have to guess. You can also choose which side to hit on usually, by slightly delaying the j2, but sometimes I didn't even know what side it was gonna hit on. This is criminally underused, and besides foxy, I haven't seen anyone use it. Idk who found the tech but credit goes to them.
