Also:

"Behold those who transact on Transfinite Levels of Existence which humankind will not even imagine for tens of thousands of years."
Basically stating that Marvel Abstracts exist on levels of reality which are beyond anything human can conceive, or will even imagine for tens of thousands of years.
Obviously that means that all of them, including the Watcher, are Tier -1, right?
Or at least 1-A, right?
Obviously not. Not only is "Being beyond any physical or scientific theories" only High 1-B (See the Downstreamers), but this is obviously an absurd claim that needs to be dismissed as such. The people writing it had not even the faintest clue of the implications it carried, and applying it contradicts everything.
We cannot use vague statements like "Beyond physics" to say someone is 1-A.
Do you have the faintest idea of how many characters are "Outside the laws of physics"?
Hell, there are characters who are not even Planet level who have that. That just means they can warp and distort reality.
In the Akasha's sense, that just means it is beyond anything physics entails in the Nasuverse, which goes up to 6 Dimensions.
Ergo, it is 7D.
