I mean, them getting a bit of help would be understandable but so long as they split up the Yonko, I can see them pulling a win. As things stand, they can't win, the series is making that clear but once Big Mom and Kaido aren't together, we'll likely start seeing the 'Novas land significant blows. The fact that they're still going against Big Mom utilizing all 3 of her top homies and Kaido in his hybrid is already quite an achievement. When Oda starts focusing more on the rooftop (whether that's next chapter or chapters from now), we'll likely see them doing much better. All of them are still up so that's something.
