New jump loop is j.B(1)>delay j.A>j.B/j.C. I think it works on everyone it worked on in EX, but I'm not sure. I see less players do it and just go for the corner carry with 5c>6C.
I don't really like that route much, because I think you can do more damage using j.236B>j.D~A>j.4D~A>6C (which is really height dependent in EX and I assume CP as well unless A cancel got buffed recovery.
I'm pretty sure j.2B was slowed down. When I see a Tao chain j.B into j.2B, it hits much closer to the floor (and doesn't combo). Also, I think you need to do uncharged 5C, since the longer hit animation makes characters shorter.
