You are completely wrong. You land a jump in on a standing opponent but you're too far away for 5[C] > 6C wallstick, you want to go for jump combo to get them to the corner with the 3C> 22C > 6D~6 > 4D~a> taunt ender (works midscreen vs some characters, corner only vs majority). That is infinitely better than forcing restand midscreen, imo.
Also those rejump combos are pretty interesting, I just do 5C > j.B > j.C
The characters I couldn't get it to work on were: Noel, Taokaka, Izayoi, Platinum, Bullet (I think), Jin, Noel, and Kokonoe.
I usually do 2B > 5B after I land from j.c in my string to push my opponent closer to the corner, I need to experiment and see if there is a way to do rejump that will save my 5[C] > 6[C] so I can go into 214D~ j.D~B for safejump ender. Too bad rejump not worth trying in netplay, so I only do it offline.
