I have played Jin's Noel and ragna's
in the 60's to the 70's That are completely stupid
Jin's Ice car in (Ib 360/720 till dead)
Noel's Drive spamming which sledge, ib 360 720 agian
and ragna's that just hell's fang or gauntlet hades in and I can agian Ib 360
ALso have fought ragn's that IAD in with C backdash 360.
Level means nothing and some of these guys had 60-70% ranked win ratios
Ironically after I perfected them they won't fight me any more.
My personal fave is Noel's spamming D and of course 236A/B/C is a joke too. Block/360/720/backdash and sledge respectively. Don't let her corner you.
Sloppy Nus are also fun.
Rachel's 214A and 236A/B/C can be sledged through all day, but you've gotta watch out for 6B and 6C with wind. Her offense can be easy to break through (esp. w/ noobs) and she has only one or two combos to punish you in close range.
Hakumen spams C all day and uses one or two combos. Not too hard here if you trap him in a corner. BC, 236B, C, D, 236B (if he falls back, then he faceplants), A, A, A, AC, then whatever.
