Change of topic but,
Should switching input method mid-set even be allowed? I feel like you should be locked in your input choice for at least each set, if not the whole tourney. Switching around could offer a tactical advantage, and we should assess whether its a fair one or not.
For example, controller Kirby has more aerial mobility and is better for air camping, and kb Kirby has an easier time pivot utilting, and is better against falcon (just a possible example, not sure if its totally accurate). If this is true, changing input method mid-set could really disrupt the opposing players spacing and rhythm.
