(spoilers)Zamasu Arc shouldn't have come before Universe Survival Arc and here's why:

[FoolsGil]

Reason: Sorting Algorithm of Evil which is in layman's terms "Every arc the villain has to be stronger than the last."

Looking to the current arc There was that exhibition match where Goku fought Toppo and Toppo shrugged off SSJBlue. Previous episode revealed that there is a God stronger than Beers, and there is a mortal stronger than that God. (I'm assuming it's Jiren.)

So how did Black and Zamasu conquer and kill every mortal in all the other universes, when folks like Toppo and Jiren existed? Black didn't even fully understand Goku's body or get access to SSJ Rose until he fought the real deal, and even if Zamasu is immortal (and that doesn't matter because he can still be sealed,) Black isn't. If Black did wipe out beings like Toppo or that strongest mortal, then when Black followed Trunks to the past, he should have been able to wreak a lot more havok against Goku.

In hindsight, Zamasu and Goku Black should have came after the Universe Survival Arc. Zamasu taking Goku's body after a tournament where we met the strongest fighters in a bunch of universes, where we will see Goku reach another plateau of power, Then yeah, Goku Black wiping out the other universes would work. Where it is now? No.

It was never said that Black and Zamasu wiped out all the mortals.

[Misirius]

It was just said that Goku Black and Zamasu killed a number of mortals on some planets, not that they had wiped all the mortals as of coming to Earth.

[Chuquita]

That would've been two tournament arcs back to back though (Champa then Omni). They'd have to invent something else to take the Zamasu arc's chronological place just to keep it fresh.

Other than that, I'd be ok with it.

[Doctor.]

It was just said that Goku Black and Zamasu killed a number of mortals on some planets, not that they had wiped all the mortals as of coming to Earth.

It was said, in the anime, numerous times, that they were close to completing their plan and that the plan would be finished once Earth was eradicated.

Regardless, I don't think it's a big deal. Jiren and the others could have died from natural causes in Trunks' timeline.

[FoolsGil]

It was never said that Black and Zamasu wiped out all the mortals.

Based on the way they talked, it sounded like mortals on Earth in U7 were the last ones, and only because they were lazy.

Immortal Zamasu could have taken care of most of their enemies. Though Black only said he had already wiped out many humans before the earthlings, so it was never all the other humans.

"Every arc the villain has to be stronger than the last."

They don't NEED to be stronger, it all depends on how later fights are executed.

But this is Dragonball we're talking about. They don't need to be stronger, but they will be.

Then why state your reason for why Zamasu should have come later to be that the villain needs to be stronger with each arc?

[dragon boss z]

The manga confirmed Earth wasn't the last stop. If the anime ever said it was then it was a Toei made up line.

Because Toppo, Jiren, and who knows what others would have killed Black and make Zamasu wish he could die when they went into the stronger universes. Black's higher power level only came after he went up against Goku.

Trunks's timeline is 17 years in the future, we have no context to judge if Black or Zamasu ever went up against any of these characters. Only that they have been to other universes.

Also, this doesn't answer my question.

I did answer your question. Zamasu and Black would need to be stronger than the previous arcs opponents, because their story involves going into other universes and killing everyone. You say there is no context to judge if Black or Zamasu went against them. Well Black and Zamasu talked like they did wipe out the other universes, and if they did, they would need to be stronger than the folks in the current arc or they would have been stomped by them. I can't explain or answer your question any better.

[Zamasu55]

Merged Zamasu wasn't stronger than Beerus. Jiren is. This means that Jiren's gonna be a lot stronger than Merged Zamasu.

[Bullza]

They should have had other sagas prior to this one to be honest. It would have more potential to be better had they waited on this.

There's 11 other Universes and prior to this saga we knew a bunch of characters from Universe 6 and Gowasu and that's it. They needed more sagas before this to build up more characters.

They rushed into this way too soon.

[FoolsGil]

Merged Zamasu wasn't stronger than Beerus. Jiren is. This means that Jiren's gonna be a lot stronger than Merged Zamasu.

In a way that helps my argument, there's no way U11 would have fallen against Zamasu if his arc came before this one. But. I do believe Goku will defeat Jiren or tie with him. So if the Zamasu arc came after this arc, he would get access to a far stronger Goku that could in fact wipe out all the universes inhabitants.

[MagmonKai]

Merged Zamasu wasn't stronger than Beerus. Jiren is. This means that Jiren's gonna be a lot stronger than Merged Zamasu.

Where do you get this knowledge? You're just making up stuff based off incomplete details. No where is it stated that Jiren is stronger than Beerus. Hell given the OP Jiren won't one shot Goku which he should be able to do if he's stronger than Beerus!

[MisteryOne]

Considering SSB Goku was able to surpass Merged Zamasu in a clash beam (which doesnt make sense, but well), and that Zamasu didn't use any Kaioshin ability, Black was a shitty SS2 tier and even after all Merged Zamasu is somehow weaker than Beerus and not inmortal at all...Yeah, in the anime is a pure nonsense (if Earth was the last place they went, thats it). In the manga, Earth was not the last planet.

Anyway, Super definetly feels rushed. A villain of the magnitude of Zamasu (with all the kill all the gods stuff) should have been for the last pre-EoZ arc. After Champa arc we should have gotten at least two non-tournament arcs, then US, then maybe other one or two arcs and then FT arc. It would have made Zamasu feel like an intimidating enemy (well, in the manga at least, in the anime he's surpassed by smoke bombs and prefers to drink tea instead of killing Trunks) since he would be stronger than the Hakaishin by himself. He would have felt more beliable after seeing Goku's «evil» actions in the US arc. The US arc itself would be better if we knew more about U6 or other universe's fighters as well.

This being Dragon Ball, where enemys/rivals keep getting stronger and stronger, the author should have a bit of planification or at least realize that the rivals at ToP should be weaker than Zamasu in order to not make his plan stupid. Anyway, I suppose you can use the «other timeline» excuse.

[Zamasu55]

Merged Zamasu wasn't stronger than Beerus. Jiren is. This means that Jiren's gonna be a lot stronger than Merged Zamasu.

Because the mortal Whis was talking about is clearly Jiren. And the opening is meaningless, plus Goku will probably have a new form.

In a way that helps my argument, there's no way U11 would have fallen against Zamasu if his arc came before this one. But. I do believe Goku will defeat Jiren or tie with him. So if the Zamasu arc came after this arc, he would get access to a far stronger Goku that could in fact wipe out all the universes inhabitants.

Well, Black Goku probably attacked the Kais while they were alone or something.
