So I did more training mode because I want this in my life.
I've actually never played brawl (I do have it thanks to PM) so I've tested it in that game as well.
It literally took me 2 minutes to get consistant at this on brawl.
So there must be something going on in the way that smash 4's processes inputs.
Turning Alternate smash on/off doesn't matter.
Alt. smash is Smash4 exclusive and changes priority of your moves. If you press A+B with alt.smash on in the air you get a N-air, without it you get PK-freeze. So, naturally you'd think that this makes it impossible to wavebounce since Attacks prioritize specials right? Well, not really. Apparantly the C-stick (When put on attack) doesn't give 2 cents about your attack input and just does what he wants. When L is changed to specials and Up-taunt to attack you can use L+Up-dpad to smash. But you can't use Specials+C-stick to do a smash so that means that C-stick doesn't do what it tells you it's doing what leads to this.
Changing Attack/Smash on the C-stick matters!
For some weird reason putting your C-stick on Attack results in a wavebounce PK-freeze. This makes absolutely no sense because you are infact holding forward and pressing Back thanks to the C-stick. Because C-stick+Special doesn't give you a smash ever you can test if your inputs get through or not and with attack they don't but on smash they do. However on smash you always get a B-reverse instead of a wavebounce and after even more training mode I've finally cracked it why it kept failing.
Brawl's troubleshooting still applies
- You do a short-hopped Bair (c-stick too early)
- You do a SHPKF, no wavebounce (c-stick too late)
- You PKF backwards but don't turn around at all (C-stick too late by 2-3 frames)
- A full-hopped wavebounced PK Fire (held your Jump button too long)
- Any combination of the above
But this needs to be added.
You do a Wave bounce PK-freeze. (Put C-stick on smash)
You PKF backwards but don't turn around at all (Held the C-stick too long)
The reason is very simple. In smash 4 you can charge your smash attack with the C-stick alone. It seems that the C-stick keeps pushing a direction and seeing how fuzzy inputs aren't a thing in smash you keep facing the wrong direction or when you do Attack no direction at all.
