Okay. No problem.
I disagree, since nothing was stated about being able to recreate the entire universal continuum according to their whims, just the local galaxy, and even that was not clarified if it would be a very gradual feat. It doesn't seem explicit/self-evident/reliable enough for my tastes.
I am currently uncertain, as it was an unproven statement with unclear specifications regarding how it would be accomplished.
I think that has to be interpreted as a regular everybody can fight everybody in order to make western superhero stories work issue, so I disagree. As I mentioned above, it was perceived as a massive event when post-Crisis Superman was powered up so much that he could move Pluto during the Our Worlds at War event, whereas Superboy Prime could withstand a point blank universe-destroying explosion.
It was an unproven statement, and we do not know if it would have been a gradual feat, but Kyle was powered up far beyond the rest of the Justice League during the first time he took the name Ion, which was unrelated to the entity of the same name at the time.
Yes, but it should only scale to regular Wally, who we consider to be tier 4-B, not "let's bully the Anti-Monitor" peak Wally.
Yes, I somewhat agree, but it is not sufficient with one occasion in order to upgrade all the herald-level characters.
I disagree. He was apparently bound with 10th Metal chains at the time, which work like superpowered Kryptonite against him, and Superman could not do anything against Barbatos without this crutch during the preceding Metal event.
