Here's a relatively short, sweet and lazy summary which addresses everything that's going on in this thread currently.
Here's the OP which explains my intentions and
here are multiple after posts of mind which explains those intentions in more depth.
The general gist of these messages is that we either need to remove HDE from the profiles for possible inconsistencies with Low 1-C in the verse, or upgrade everyone who's currently 2-C to Low 1-C since their 2-C scaling is contingent on Adolla, if Adolla's a 5-D dimension, with it having a qualitatively superior existence over the 4-D dimension of the main Fire Force universe, then the manipulation of that dimension would be a 5-D/Low 1-C feat, similarly how it's currently considered to be a 2-C level feat in conjunction with the main Fire Force universe.
Duedate has expressed disagreement with this logic in a multitude of posts.
The general gist of these messages, in my observation, is that Duedate believes Adolla's existence can be 5-D but wouldn't necessarily impact the current 2-C scaling that verse's God-Tiers since HDE within itself doesn't grant a tier of physical power that's equative to the level of existence that HDE provides.
While this is generally true, Duedate is, in my opinion, misunderstanding how HDE, in function, interacts differently with dimensions in comparison to physical entities, when examined under the context of stat scaling. If a dimension has HDE, because it's 5-D in existence, then manipulating that dimension with pure power, or abilities which scale to one's physical stats, would be a 5-D/Low 1-C feat. Simple as.
I'm not arguing that since something has HDE, it necessarily scales to that level of dimensionality in power. What i'm arguing is that since Adolla's considered a 5-D dimension, and the current 2-C scaling is contingent on the manipulation of Adolla, alongside the main Fire Force universe, then it necessarily follows that manipulating that 5-D dimension with an ability that's considered applicable to one's stats, would cause that entities stats to be 5-D/Low 1-C.
Here's Maitreya's post in regards to why HDE should stay, everyone can read it themselves, i'm not going to give my opinion on it.
There's also the main post of Pain on why HDE should go, and
her response to Maitreya's post, like with Maitreya's post, i'm not going to give my opinion on both post.
There, that's basically everything of note going on in this thread, hopefully this helps the process of evaluation for the mods who might comment on this thread.
