QCF is the wavedash itself. A forward input in between QCFs cancels it to let u do multiple quickly. So multiple wave dashes would look like
QCF F QCF F QCF F QCF F
Each char with a wavedash only has so many options out of it so familiarize urself with yours. For example basically everyone with a wavedash has a quick mid check in wr4 which they can do from it.
U r high evading when u wavedash so also don’t be afraid to do single ones at a time.
U have a little time at the end of ur wavedash to input whatever u want. The buffer is slow.
U shouldn’t try to high evade electrics on reaction for a variety of reasons, it protects u from getting jabbed out of it, if the opponent is reacting to movement your single wavedash has enough frames to protect u. If you are spamming it and canceling it early it has less frames but once again the buffer is slow.
U can realign with a single frame of F input as well
Everyone is looking at the screen though because they’re playing the actual game. Practical application of wavedash is super nuanced so the advice for new players should be “don’t be eager to spam it in someone’s face because they can challenge u with any mid” but if u are spacing ur wavedash approach options “perfectly” that’s not on the table for them
Oh, you're talking about a single wavedash-guard being uninterruptable on reaction! Yeah. High evade isn't why that is, so I mistook what you meant: I meant more "don't WD into a keepout electric and expect to evade it". Indeed. New players tend to think of wavedash as this Ultimate Mishima Technique and use it on people who don't have the defense to justify a pressure tool like wavedash.
Personally I think learning principles like dash-guard makes it easier to conceptualize stuff like wavedash-guard: in a lot of ways WD is an extension of fundamentals like how to approach or how to apply delay timing pressure. It allows you to put in execution to do these things in a more effective form, but you gotta know why you're doing them.
