After a jump in punch i'm currently doing 3,D+1,2, Dash, 3,D+1,2, Dash, 3,D+1,2, F+4 (41% before any patches ) but at the moment you can also do 3,D+1,2, Dash, 3,D+1,2, Dash, 3,D+1,2, Dash, D+1, Smoke Bomb, X-Ray (50% before any patches ). You can continue juggling after the Smoke Bomb also but i haven't really explored that yet. I read somewhere on this forum that some people were having trouble getting 3,D+1,2 consistently, they keep getting the 3,2 launcher instead, the trick is to pause slightly after doing the 3,D+1, if you do the inputs too fast it seems to miss the 2nd input.
I love doing 3,D+1,2, NJP, Jump Kick, Air Throw, OTG Smoke Bomb, Dash, 3,D+1,2, F+4, it's my favorite combo, sucks that it's not going to work anymore. I don't understand NRS taking it out it's not OP & adds variety to his gameplay. This could potentially ruin the character IMO :\
