Rosalina has an easily intercepted recovery, how dont you know that yet? It may be fast, but simply timing an easy stone can kill Rosa at 80%, you can even use a d-air for a guaranteed kill if you follow it up at LOWER percents.
I never said Marth outranges Rosa so it's bad for Rosa. Marth's range leaves Kirby at a disadvantage. Rosa does have good range/disjoints (u-air and d-air come to mind first), but overall Marth has more and more USEFUL against Kirby. Rosa's range outranges Kirby, but not enough to create a disadvantage about it.
What I mean by "Counter people with that impression" was that if people think Kirby's range is too short, first they're wrong and second they are using the wrong mindset. When Kirby gets in (which trust me, he will), they will be going on a wild ride, since Kirby's combos are what puts him back in.
Have you ever faced a good Kirby? I extremely doubt it.
F-air and b-air actually have ok range, d-air too, only u-air is the stubby one. F-smash has reaaallyyy good reach too. U-air and U-smash are stubby but useful, but d-smash is situational.
Anyways, Kirby simply has too many tools to be considered 30:70. Early kill setups, a ton of luma pressure, easy off-stage kills (no customs, but with customs the score would stay the same), etc.
Kirby is one of the most controversial characters in Smash rn, in SWF Tier List he got -7 +6 or something, second most up votes and down votes in his tier. Some lists put him high, some low. All Kirby mains in this thread haven't gone down past even 40:60, and one of our best Kirby mains voting 70:30 in Kirby's favour.
My vote is 50:50, and so far you've given so little points except for range, and "this point is kind of sort of inaccurate-ish!".
I think this is only slightly in Rosa's favor 60:40
Lets be honest, kirby actually fares pretty well against most of the top 10, like sheik or villager or (sometimes) Diddy.
Kirby's lack of range isn't as big of a problem people think. To me, its generally his approach.
But Kirby has the lowest crouch correct? This I significant in MU like shiek or ZZS, where if they can't use their projectile or land some of their attacks, he has the advantage right there, his attacks in terms of speed, is comparible to the other characters.
He sometimes doesn't have to approach, but space, poke and punish, or even force the opponent to approach him.
Now Rosa, she is defensive, and Kirby is likely go into have to approach, let's be honest Rosa's approach nor ability is really any better then Kirby's because some of her attacks are easy to dodge and punish and Kirby has faster attacks overall(on the ground at least) So Kirby will rely on punishes and separating her from Luma, which isn't too hard,
What we do suffer from her, is her Uair, Utilt Usmash, because we do have a hard time landing without getting hit from one of those, but our multiple jump slightly compensates for that.
She is.... Not TOO difficult to edge guard because if they go for Ledges just try and time something like a nair, and because she goes so high, if she goes onstage she may still be in the animation before she lands taking additional lag.
Luma will be a hastle if not taken care of, but in a way, our Lima(if we get inhale) may be superior because of its knock back and I think it out powers her if you were to release it at the same time
I can't explain much more typing on this tablet is too annoying.
Overall I think Rosa still has this, but only ever so slightly because we can still hold our ground.
