Again, you do not have any experience with homemade deep notches, but you say they should be allowed.
Again, you make this claim that isn't true. At this point I wonder if you have read any of my posts at all.
When they make the success rate of executing perfect wavedashes unmissable (saying "virtually" just seems inaccurate), that is a super-human success rate. If you make the notches correctly, and you are average at wavedashing, everyone on Earth will miss more perfect wavedashes than you. It's literally just as easy as dash dancing.
Missing the angle is practically impossible (though still happens occasionally), but that doesn't guarantee a person the perfect wavedash. They still must jump, move their control stick to the proper position, and then airdodge on the first airborne frame. The controller notch does no work for the player, it only acts as a guide.
Are steroids a personal nutrition choice? Remember, everything that has ever been achieved by an athlete on steroids can also be achieved by a clean athlete. Is this a solid argument for steroids being fair?
To people that understand this game, it's no secret that making small improvements in one's game can yield significantly better results. But this is irrelevant. If you cheat on a test and get a D+, you're in just as much trouble as the guy who got an A by cheating. Whether the unearned advantage gives you the win or not, it should still be banned.
You keep calling it a cheat without any argument to classify it as a cheat. All the comparisons you make are bad analogies. If you want to compare to something, compare it to what is banned by the FGC or what is banned in Smash.
In smash there are currently two groups of mods:
Group 1, Legal:
Anything purely cosmetic, stick box swapping, button shortening, trigger modifications, controller notches*.
Group 2, Banned:
Turbos, macros.
The only reason a mod/feature is currently banned is if it performs multiple inputs for the player. Quality of life mods are not banned, and being an abritrarily stronger QoL improvement is not enough reason to move controller notches to Group 2.
Agreed. At this point we are starting to test in tournament for one's ability to alter controllers and make the game less technical more than ever before. We are introducing the idea "why work hard to strengthen my weaknesses, when I could alter my controller to hide them?" No one will use a configuration that makes the game more difficult. They want to make the game easier for them to play in order to gain an advantage. This may seem harsh or extreme, but it's true.
The game exists beyond the controller barrier. Surprisingly, the most technical player in the world is not the #1 ranked player. Strategy, patience, dedication, persistence, perseverance, creativity, hard work ... these are things that matter in terms of winning the game.
And I have to point out that the industry trend is towards customized pads and fight sticks. If those custom controllers are legal, then controller notches are a no-brainer.
Not everyone knows how to properly notch a controller, nor does everyone have the money to spend on a notched controller. Now, entering a tournament and competing on an even playing field requires either some controller knowledge and the skills to properly modify one, or the extra money necessary to buy one. Even if you don't buy one, you will have to purchase tools, and hope you don't ruin your controller front piece on your first try. The "equal access" argument is not exactly accurate because of this issue.
All of that information exists and is public. There are tutorials on youtube created by Kadano himself. You can purchase the service from an expert if you are unable to do it yourself. Is playing a technical Fox not "equal access" because newbs haven't figured out how to deal with it or copy it? Is it cheating to pay an expert for 1on1 lessons?
