Holding the C-stick does nothing.
Therefore, if this works when just holding the C-stick diagonally, then either (a) the C-stick is not actually involved, or (b) EIDI needs just one input from the C-stick, which it will accept in any part of a huge interval.
Due to the improbability of the latter, I suspect the former.
Some questions:
- Does it matter if tap jump is on?
- If you do this input from a neutral position, what happens? Do you reverse Fsmash, do you utilt, or do you do an aerial? Do you perform an empty jump (or do nothing with tap jump off)?
I'm particularly interested if the answer to 2 is "it varies by how exactly you flick both sticks."
See, because, I am incredulous that this input somehow works, but everything that people have been doing up until this point hasn't. I
know people tried tapping away from Marth. You say this input is really simple. How could you be the first person to try the diagonal?
I'm not doubting
you of course - I'm trying to explain the mechanic.
