Noa.
Characters I've seen be wrecked by Rosalina are hard for me to feel confident as top 5, although Fox can definitely argue it (and I've argued it before).
Not sure how much the jab nerf hurt him in some of his close/other high tier match ups.
And eh, national within the context of the US? Maybe not.
National within the context of Mexico? It would be incredibly silly to not agree. Mexico is completely off the map for most of us and it shouldn't be (and their players don't seem to be fans of them being ignored/underrated either).
Sheik is a big factor to my "theory". I originally felt (probably still do) that Sheik/Fox isn't bad for Fox (heck some results would indicate Fox advantage). As the jab lock never really applied to Sheik it's probably a net gain overall. Sheik players seem to be growing still while Fox does seem to be slowing down, although not certain, I'm just currently aware of more things that get in the way of Fox than I'm feeling towards MK.
His rise will plateau at some point.
For what it's worth it's hard for me not to think of Sonic, Rosa and Fox as high/top-tierish still.
