Doesn't matter how hard it is to do, someone can put in enough practice to be able to use it for the length of a match. You can't base things around the enemy messing up. If that were the case, a whole bunch of walk off levels would be legal in melee because wave shining was "hard" and the player would "probably" mess up before they carried you off the stage with it.
Not the same thing, that was a horrible reference. Walk off levels were banned because it was an instant kill, if a fox had enough skill to waveshine.
This techinique doesn't hurt the opponent, and if someone, like you said had amazing zero limit skill and COULD hold it for a while it wont hurt the opponent. Also this is many many times harder than waveshining. I know from experience.
Also if the enemy tries to attack simply shield.
An easy response to an amazing player doing this is just spam roll.
if they attack you shield and get a free grab.
If they don't you roll and the battle sequence resets, either way this is not broken or banable.
This should be better referenced as SHDL because it is about the same difficulty to perform.
Have you even tried to use this technique in a match or just in practice?
it is hard, and has no offensive applications besides mindgames.
also stages are normally banned so characters are not banned.
If we let walled stages exist we would have to ban all characters that could infinate chain grab.
Edit:
If we kept items on during tournaments, or allowed every stage, then when we have a winner, whose to say it was or was not because he used an item or because the stage killed his opponent. But with a technique like this Meta Knight thing, it'll be very obvious if we see all or most tournaments being won by Meta Knights abusing this technique.
We have never before faced a technique with this much power or controversy. If this tech is banned immediately without ever being allowed in a single tournament, then I question if we have the right SBR members.
This being banned is a joke
this tech iis difficult and has little application.
I'll say it one more time,
Unless the enemy stays still and does nothing,
THIS TECHNIQUE CANNOT AND DOES NOT KILL.
in most cases it does not even give you an advantage rather gives the opponents a free hit.
