I've actually thought about it and, in truth, Kirby doesn't really lack that much range. His attacks have the same general range as Fox/Falco, his Bair has good range/priority, his grab range is good. Range isn't his real problem(it's Pichu's real problem) His real problem comes from the fact that he can't do anything with what he has. His grab range is huge but his throws are ********. His tilts are all on standard level, Utilt Juggles, Ftilt removes pressure, Dtilt edge guards well, but they don't anything else. he can't follow up a tilt with anything because he's slow, but he can't expect to kill with any of them(except maybe Dtilt) and his only combo is out of Utilt. His smashes all have ******** hitboxes meaning they don't do what you want when you want unless you're incredibly precise. His aerials are okish, what he has works, it just sucks that HE has them. If Jiggs had his Uair and Dair she'd be even more dangerous(well, Uair is debatable as her's has Rest Comboability) His only good special is Inhale(which, if used correctly is actually an amazing move, but no one knows that because no one uses Kirby
)
Kirbykaze, you just suck at recovering. Stop playing Sheik with her 1million invincibility frame Up B and learn how to recover like the rest of us.
