This can't really be 'fixed' since this arc is broken on a foundation level.
-This arc depends on Beerus losing all the development he gained in the anime and not caring about doing his job after his poor management nearly got U7 erased.
-UI Omen in the anime doesn't work like the manga. So Goku achieving it and not the completed UI forms makes little sense. Especially to the point that Goku had to lose all his fighting IQ to make the fatal mistake that made him lose Omen because Toyo decided from the Universal Survival Saga onward that Goku's a muscle head who only wins by 'meh, more power'.
-There is no way they can explain how Goku and Vegeta can be knocked out for three days and Moro not gathering all the Dragon Balls and also keep out the utterly BS 'I can sense Dragon Balls all the sudden' when the heroes grew a brain and decided to hide the Dragon Balls.
-How Frieza's henchmen gained access to the Dragon Balls via some random mind control device he had on him since he somehow knew that he needed a Namekian unlike his boss and killed the Elder Namekian who off-scene gave the power of the Dragon Balls to Denda-lite for no real reason.
-Moro's second wish sucks.
-How did all the prisoners know where Namek was when the remains of Frieza Forces couldn't find it despite searching for nearly a decade? And how did they reach the planet so fast? Like, it took days for Moro to reach it after his prison break.
-Meerus is an OC with all the horrible traits of one you would see in a fanfic and giving him a good voice aren't fixing this.
-73 is literally just Hit with creepy eyes and horns with an ability we have seen dozens of times in Dragon Ball.
The only salvageable thing in this arc is Moro, and that's because they can keep his personality as bland as rice cracker and just give him awesome magical techniques like how they turned Merged Zamasu into a RPG boss or how they diversified Hit's Time Skip. Although, even that will be short change after Moro eats the Hit knockoff and turns into goat version of Cell and get the played out 'I can regen' Dragon Ball super power.
Also, they never did explained why did Moro randomly gained some of his power back when he was closed to dying of old age.
Overall, they would have to rewrite this arc from the ground up to make it work, but Toei is never going to do that. Instead, we will get something like the retellings where some stuff is made better, while other feel worse, and the end we're still left with a heavily flawed story that only redeeming traits being good music, hopefully great animation, less weird dialog, voice acting, and art that isn't Toyo's infamous broke bodies. That and UI actually dodging.
