Since option 3 and 4 were added, I was asked by Ant to check whether you maintain your vote for Option 1 or not, as the majority did that before we introduced 3 and 4. Including you, unless I missed something, if then sorry for that.
Option 3 :
1-C remains unchanged
The current 1-B becomes Low 1-B
The current High 1-B becomes 1-B
High 1-B becomes the tier for up to uncountably infinite higher planes/dimensions/stuff
Low 1-A: More or less a better defined current "baseline" Outerversal, up to any finite number of higher levels above it.
1-A: Infinite Outerversal Hierarchies. Though it doesn't necessarily have to be layers/levels, sheer power/size equivalent to this also qualifies
High 1-A: Denoting characters who exist above Outerversal hierarchies altogether, and lie beyond any scale.
0 becomes a tier for all-encompassing characters who exist fully beyond the scope of the rest of the system.
It's basically the higher tiers of Option 1, but without the disadvantage of compressing the lower tiers.
TL;DR : Option 3 = Option 1 Outerversal and above tiers + Option 2 lower tiers. (Or Option 1 but decompressed in the lower tiers)
Option 4 :
1-C and 1-B are unchanged
Low 1-A becomes the tier for uncountably infinite dimensions
1-A remains baseline Outerversal and up
High 1-A becomes the tier for transcending outerversal hierarchies
0 remains the same as the above
Outerverse level has its definition changed from primarily being about existing "beyond-dimensionality" to existing in abstract states of being which cannot be reached by stacking lesser infinities together. Simpler + more straightforward.
The higher parts of the system itself start to have a defined metric as well, namely, Aleph Numbers. To give you a brief primer on what they are and how they work, I'd need to establish some important distinctions here: Primarily, one between Cardinal Numbers and Ordinal Numbers.
They'd end up with basically the same AP section as Oryx, given that they killed him, Crota, the Deathsingers, Atheon, Panoptes, and Riven. The "eventually" comes into play because Callus predicts that we will one day destroy the entire vex collective.
