A very clear example of this is that the Moro and Granolah arcs didn't establish any new recurring characters that would appear as key characters in future stories even though they were perfectly set up to do so.
Take Merus for example, the angel turned mortal, we haven't seen any of him since the end of the Moro arc and the Titular Granolah from his own arc, hell in his case Toyo didn't even bother giving us a throw away line that his wish to be the strongest would be undone so I guess he'll be dead by the time EOZ rolls around.

This is very different to the original manga and the movies written by Toriyama wherein each story would give us a new member of the core cast to help fight in future battles. This list includes: Vegeta, Piccolo, #17 and 18, Fat Buu, Uub, Freeza, Broly and I'm certain if a new DBS movie comes out Gamma 1 and Dr Hedo will be in it.
Another thing is that even the "development" characters go through (let's be honest mainly Goku and Vegeta) seem to be swept under the rug. Remember Goku mastering UI and being complemented by Beerus stating he "Fights like a God" just for in the Granolah arc Goku's perfection of the Silver Haired MUI for to be removed because of arbitrary time-limits and he can't "keep his heart calm in battle". But I guess you can't continue to milk Goku if he no longer needs to develop as a fighter lol

Also remember Vegeta's training on Yardrat? A shame his forced spirit fission training is literally never brought up again after the battle with Moro, I even expect UE to quietly be shelved as it turns out Vegeta's original transformation (which just got beaten up the entire arc and didn't accomplish much of anything) was just hot air and now he's focusing on meditation as that's the way Toriyama wants it.

But at least Toyo managed to tie it into Vegeta's meditation stance on Yardrat, that's cute.
On that note it's kinda hilarious how Toriyama just supersedes Toyotarou especially now that the manga is adapting Super Hero, Toyotarou clearly wrote Gohan to have his head in the game since the TOP and kept up with his training and never used Super saiyan but nope now in the Super Hero arc Gohan has been a slacker who has to rely on super saiyan and re-unlock his Ultimate form... again.
Also going by the manga's continuity Goku and Vegeta surpassed Broly during the Granolah arc

but nope now Broly's power is a threat to Goku and Vegeta and even worries Beerus


also Piccolo speaks of Goku and vegeta as equals power level wise when comparing them to the Gammas (they're Blue level as far as Toriyama in concerned) even though in the Moro arc he saw UI Goku in action.

Oh yeah it's been a year since the Black Freeza reveal and we've heard nothing about him since...
Then there's the weird thing of Toyotarou's work barely being featured in any videogames or other Dragon Ball merchandise like figurines.
All of the above makes his manga arcs look like nothing more than glorified fan fiction that Toriyama sometimes glazes over but ultimately doesn't pay it much mind as it never touches broader Dragon Ball, it's in its own bubble that can't really change the status quo and can be ignored and discarded at a moment's notice.
