Nope, pretty sure everyone knows. When I was trying to hold down to get a fastfall input, it mustn't have buffered it yet, then when I input the dair, it still does nothing, causing me to die at earlier percents.Also please tell me that the fast slow/fall mechanics of smash and tilt sticks being reversed if you hold down on the analog isn't considered a new concept. Kirk had used it a number of times to walk off dair without having to change his controls.
Because I tried to be very precise with my inputs, I basically did the same thing over and over 20-30 times, which gave me a false impression.
