Not sure how this moved to the Social thread, but this does give me the opportunity to say a few things without derailing the MU thread.
70:30 is pretty insane, almost as much as that 75:25 verdict vs Bowser. Like, seriously. Rosalina is not a powerhouse. Her performance mainly hinges on staying safe and not getting caught in anything. The entirety of her MUs is based on who can break her defense.
And honestly, that defense can be broken as long as one remains patient, as skills increase across the board, more and more players are starting to realize that Rosie is actually pretty weak without Luma. In nearly every tournament, Rosie players stalls, rolls around, spotdodges, and platform camps until Luma returns.
Now when Luma returns, what matters next is, has Rosalina reset the situation? Because if she did not, Luma returning doesn't mean anything. There has been more than one time that I've witnessed Luma being immediately KO'd right after respawn due to being in a terrible position. This has happened to myself more than once as well.
So what does this mean, exactly?
It means characters that are able to keep pressure on Rosalina will be the ones that give her a hard time. This means all the top tiers, plus Yoshi, Luigi, Mario, Peach, and so on will have better MUs against her than others who rely on defensive, slow-based play.
Doc doesn't have this ability to keep pressure onto Rosalina once he gets inside, and that is solely because of his poor mobility. That said, 70:30 is a stretch because Doc is capable of racking up damage fast once he does get inside, and he requires less reads since he has plenty of KO power. Plus he's not
that slow.
I don't think any of us are pushing it as even, I'd say it's more like 60:40 because Rosalina can still zone out Doc without Luma. I think the reason why some of the Docs here are pushing the matchup as more favorable for Doc than it is for Mario is because the ability to kill Luma easier than Mario makes approaching easier for Doc. Mario has to deal with Luma since his only options for seperating Rosalina and Luma is a reverse USmash, DSmash or Back Throw. As far as I'm concerned, Rosalina can still fight when she gets approached so Mario being faster or Doc having a better projectile doesn't really mean each Mario is better than the other. Though 70:30 is like saying Doc gets mollywhopped. 65:35 or 60:40 is better sounding.
I don't know how it is with customs, but I think Luma would tank Fast Capsule.
Also I don't know where you're getting caping from but I think caping is a rare opportunity in this game for both Mario and Doc. Doc shouldn't be caping especially against Rosalina in any case, since if Rosalina got caped then that means the Rosalina player messed up.
Mario can separate Luma from Rosalina with D-air, which is a lot easier to pull off than B-throw and Doc's Nado. It may not kill, but getting Luma out of position is enough for Mario to press his advantage on Rosie. Furthermore, Mario has a much easier time juggling Rosalina than Doc does. Doc honestly does not have an easier time taking out Luma and keeping pressure on Rosie.
I do agree on Capes being rare. It's really just capitalizing on opponent's mistakes. This is why I say Doc's edgeguarding is overall better than Mario's since Doc Nado, D-air, B-air, and N-air are much more preferable to Mario's aerials. FLUDD and Air Speed are the only wildcards in Mario's kit.
