That's kind of a waste unless you REALLY need to kill. I'm not at my console at the moment, but you should get similar damage off of:
GS B, GS B, GS K BE W!, iWR (B), NSS A+B, 2A+B and also end up with good meter gain.
In general I prefer to use iWRB in wall combos whenever possible because...
4AAA and its BE are both kinda terrible, but 236AA isn't all that punishable vs a lot of characters unless they JG the second hit. Luckily no one is doing that yet.
More A+B bait, courtesy of Hilde:
second hit of C3B; combo with A,K follow-up
second hit of C3A; combo with 236B:4
Both of these can also be JG'd, but I'm a fan of making things as easy as possible. IIRC, at the most you lose maybe 3 points of damage by using A+B instead. You can also punish...
So apparently, you can beat all of Xiba's RM options with 22K. RM A gets ducked and RM B/K gets stepped, giving you 85 damage for free. It doesn't matter which transition he uses, either. Lol, this move is silly.
Edit: Actually RM AK will hit you and he gets 3kB for about 44 damage. However...
Who are these characters with amazing lows? I can't think of many that would actually make me start ducking. It's been said before that adding a good low is probably the laziest way to improve a character.
Probably should stop posting random things in this thread lol, but I dunno where else to put it.
You have to learn to JG Asta's 44(B), or he will abuse you like a redheaded stepchild. A+B works too, but you don't get anything if it's done from tip range, iirc. It's very easy to react to the...
