I'm tired of repeating points and not having scans being presented to support the oppositions, thus I'm making one larger master comment.
Dragon Cry Isn't One Singular Blast:
As we are shown through the movie, Dragon Cry is not an attack that destroys the continent of Ishgar in one blow. There is no feat nor statement supporting this, you couldn't find evidence to back this up even. However, what we can find is proof that Dragon Cry is actually several Magical Circles a covering the sky of Ishgar and firing barrages of magical blast onto the land to eventually destroy it over time.
Zash Using Dragon Cry
Zash Activating Dragon Cry
As seen here, when Zash activates Dragon Cry it literally fires a beam into the sky and then creates the Magical Circles all over Ishgar. Zash even stated before hand "Oh Dragon Cry, show me your true power." So yes, this was in fact Dragon Cry in activation and this is what Dragon Cry does, it makes Magic Circles to fire magical blast onto the land and eventually destroy it.
Character Seeing Magic Circles
Characters Confirming Magic Circles Are Dragon Cry
Once Dragon Cry is activated by Zash, we literally have characters looking into the sky and the Magical Circles and confirm that we are in fact looking at Dragon Cry in activation.

Zash Explaining How Dragon Cry Works 3
Plus, Zash literally describes how Dragon Cry is supposed to work. He says that Dragon Cry is supposed to be reflect "deceased dragons making iron hammers of their rage to strike upon the land". He even describes how it's multiple attacks being barraged upon the land.
Animus Taking Dragon Cry
Animus Beginning to Fire Dragon Cry After Taking It For Himself
Animus Firing Dragon Cry After Taking it for Himself
Following this, Animus eventually takes Dragon Cry for himself after Zash dies. When Animus has Dragon Cry, he literally says "Dragon Cry grant me my true power" and the Magical Circles in the sky all activate and begin firing barrages of magical blast upon the land. Supporting that Dragon Cry is in fact those Magical Circles once again.
Animus Defeated Yet Dragon Cry Magical Circles Still Activated
Dragon Cry Staff Being Destroyed
Dragon Cry Going Away After Staff's Destruction
To further back this up, when Animus is defeated and separated from the Dragon Cry staff, the Magical Circles are still present in the sky. It's not until a character destroys the staff holding Dragon Cry's power that the Magical Circles go away. This is literally undeniable proof that those Magical Circles are Dragon Cry in action.
Dragon Cry's AP is not 24 Times Etherion:
There is a misconception that Dragon Cry's AP is 24 times greater than Etherion when there is no statement saying this and we literally have a feat of Dragon Cry in action that undeniably proves this would be wrong even if the statement existed.
The actual statement in question states that "If Dragon Cry is unleashed, it would release magical energy dozens of times greater than an Etherion blast".
This is where we get into the mechanics and technicalities of how Dragon Cry works. As we are shown and given a demonstration of Dragon Cry, we know that Dragon Cry is "Damage Over Time" attack, it's not a "Damage In One Shot" attack. We are given statements that Dragon Cry would eventually destroy the continent of Ishgar when it finishes it's job of barrages of magical blast. Etherion works by one singular blast that could wipe out a country.
This statement that Dragon Cry has dozens of times of magical energy than Etherion is not wrong. Etherion only has energy for one country wiping blast while Dragon Cry has enough storage to wipe the continent. The issue is the application of that magical energy. As I have shown through statements and the actual on screen demonstration of Dragon Cry, Dragon Cry would have apply that damage over time eventually, it does not do it in one go.
Animus isn't High 6-A After Absorbing Dragon Cry:
Animus Taking Dragon Cry
Animus Absorbing Some Magical Blast from Dragon Cry
Animus Absorbing Some Magical Blast from Dragon Cry
For starters, Animus only absorbs about a dozen Magical Blast from Dragon Cry. Animus takes in Dragon Cry for himself and he does amp himself with blast from Dragon Cry, but this doesn't make Animus
High 6-A. Animus only had a dozen magical blast fired onto him for him to absorb. This isn't Animus channeling all of Dragon Cry into himself to make Animus High 6-A especially since during his whole fight with Natsu while amped, Dragon Cry was still being used in the background to fire upon the land. It's an unquantifiable amp of Animus absorbing a dozen or so multi-city block magical blast.
And the most blatant proof against this... if Animus was
High 6-A after absorbing Dragon Cry why did he after absorb even more Magical Blast when he had already absorbed it? Given that Animus has two moments of absorbing magical blast from Dragon Cry, it's clear Animus didn't even absorb all of Dragon Cry for his own AP, durability and speed. Plus the fact that Dragon Cry was still being fired on the land during his fight with Natsu, more evidence that Animus had no absorbed all of it for himself. An unquantifiable amp.
Conclusion:
In conclusion, Dragon Cry is not
High 6-A as we had originally thought as it has no feat, no calc and no statement saying it's
High 6-A. Dragon Cry in actuality is multiple magical blast that are spammed over a continent to destroy it over time. On top of this, Dragon Cry does not have an AP 24 times greater than Etherion as nothing supports that and we actually have on screen demonstration that Dragon Cry works over time. No one is
High 6-A from an ability that isn't
High 6-A itself.
