Some characters get really low in their ducking animation. Why isn't this abused more? Especially characters that can crawl can sneak under a rising aerial with a reduced hurt box to put the opponent in a bad position but a low duck is already good enough.
Best example where ducking / crouching shines is against MKs approaching with dair and aerial tornado. Some characters can literally avoid all hits of the dair and about half of the tornado without even using their shield by simply ducking. If you get the timing down to spot dodge the final hits of the tornado you can keep your shield at full health without much trouble against that approach. Against a rising fair of like marth you can crawl below him to avoid a second fair or other follow ups and get a safe utilt [and a much better position]
Characters that should duck / crouch more:
Snake, Diddy Kong, Wario, Olimar, Lucario, Kirby, Mr. G&W, ZSS, Wolf, Mario, Luigi, Sheik and Pikachu
