Don't you think that 5D will hit at the right moment since they said it comes out slower? so after 6c, then the delay will cause the opp. to go back down a bit more so then it'll hit?
I usually just do the sample challenge combo since im particularly new to bb(and to this style of fighting games in general, as i came from t6) so its basically 3c, 22c, 66c, then 5d d.6b, d.5c, then j.d then 5d to 236d. So i'm actually concerned on how it'll hit.
