I am going to assume your statement is purely conjecture and that you haven't bothered playing in that style. I simply recommend playing without wavedashing to get used to spacing with the dash/shield. If you then feel like wavedashing out of shield immediately every time always and forever is the correct approach then please do so. Otherwise, maybe you could actually learn something on your own.
I just dont think that it requires no wavedashing. and it doesnt. The best way to practice it is to try it more, but I just dont believe taking out wavedashing will add to your practice or make u more reliant on the technique...such as playing falco with no laser forces u to really really think about your approaches and make your combos count.
Shield stopping, which I spent hours practicing btw(back when I mained m2/marth), isnt an alternative to a WD, if anything its an alternative to a pivot since they tend to cover most of the same functions. Most players dont pivot, or cant pivot reliably, and therefore this technique is usually additive and not a replacement for another.
The other important thing about shield stopping is that simply putting up your shield often makes your opponent think you are on the defensive and they may attack thinking that its safe or that you are going to be set. Its just another visual thing to process and when you can quickly bring up and drop your shield while moving while still being able to attack its pretty trippy on the eyes.
So for anyone who thinks Im saying that you need to WD oos everytime you shield, and shield stopping is not useful on its own(if u look a few posts down you will see where I posted about it), thats not what Im saying.
edit: at tomacawk-yea I know what you mean, I use to practice pivot anything stupid(marths pivot reverse up B). I can still pivot pretty reliably but mostly I just do bairs and jabs and ftilts(Im really really trying to get uptilt down). Shield stopping is wayY easier and not much slower.
