just to clarify: 1B BE has been nerfed.
1B BE 1B BE B+K is no longer a combo, in fact there are now no follow up to 1B BE 1B BE; the opponent just recovers instantaneously.
The only positive aspect to the new 1B BE is the opponent is better guaranteed not to have fallen on the ground thus be within range for the 6KB followup wither or not there was any funny business with countering.
1B BE 6KB still doesn't work at opponent's back or side, and in this aspect the move has been tones down a great deal:
The 1B BE has a habit of making the opponent back turn if you're even a fraction off of facing their front (go into practice mode and SS once and perform 1B BE: you'll wind up with your opponent in a back turn stun). In this instance you used to be able to do 1B BE 1B BE B+K (or possibly 8A+B, B, I never tested it) but now you're best option is eithe 1B BE 1B BE (followed for a grab or something since the opponent now recovers instantly but in back turn) or 1B BE BB. for about 55 damage.
Some players still get hit with 1B BE 6KB even with a back turned stun so I had a session in practice mode using 1B BE 6KB after side stepping and at various angles to the opponent.
The players that will reliably get hit with all of 1B BE 6KB even when you get a back turn stun are: Raphael, Aeon, Ivy, Ezio, Asrteroth, Patroklos (but NOT @ Partoklos), Z.W.E.I, Tira, Algol and believe it or not Natsu!
The ones where the 6BK either definitely misses or misses 9/10 are: Leixia, Viola, Pyrrha & Pyrrha O, Hilde, Misturugi, Yoshimitsu, Voldo, @ Patroklos, and believe it or nor, Cervantes, Sigfried and NIghtmare.
The odd ones out are Xiba and Maxi;
for Xiba it seems to be a matter or range: if he falls close and to Ivy's right then it'll hit other wise it'll miss. It's about 50/50. Maxi nearly went into the miss pile but it does hit every so often. Sigfried for example also hits every so often but far less so then Maxi. so I really only put it here as a technicality.
Before in this instance I could use 1B BE 1B BE B+K but now I gotta settle for 1B BE BB against these guys.
