'Sup, guys? I've been lurking here since, like, when the SSB Dojo launched or something. Decided to finally actually bring something to the discussion.
Anyway, as a Luigi mainer, I don't see why people want to get rid of Luigi Cyclone. It's an amazing recovery move (one of the things that puts Luigi so far above Mario in my book), and since the removal of wavedashing, it's also been the best and pretty damn safe way to cover lots of ground quickly. Smashville, for example, is really easy for Luigi to control with this and fireballs. Just saying, it's one of the best situational utility moves in the game as it can change your positioning in the blink of an eye. Keep it in, Sakurai!
