I only just found this thread, but I want to point out that I strongly, strongly disagree.
It is completely implausible to find an equivalent joule value for erasing something from existence. This sort of thing cannot meaningfully be put into our AP section, and trying to do so conflicts with other rules that we have on AP, such as this note on our
Tiering System page:
Tiers between 9-A and 3-B, even those which do correspond with their namesakes, should not be assigned unless there are accepted calculations, multipliers, and/or reliably stated precise Joule values that correspond with those ratings, as many verses can have their own context result in these feats being above or below their namesakes. The exceptions are that the lower borders of 5-B, 4-C, 4-B, 4-A, 3-C, and 3-B can be considered standard calculations for destroying a planet, a star, a solar system, two or more solar systems, a galaxy, and two or more galaxies respectively, and adding those tiers based on those specific feats is allowed.
Neither DT nor Ultima provided a solution for this problem.
When it was noted for Creation, we made
a table on the Creation Feats page to categorise the inapplicable feats, but such a thing wasn't done here, and seems nonsensical here.
If we were to draw that equivalence, why would we say that EEing a rock takes 2 orders of magnitude less energy than fragmenting it?
It's even worse hearing some people talking about EE scaling to other attacks through a UES. That just makes things even more flagrantly wrong, since rather than being a loose approximation it becomes a precise value for physical blows.
I also think that it's generally misleading, since a character with 8-B EE can still EE a character who is tier 5, as long as their body's small enough, since EE negates durability. I think that such scale should just be explained in the range section, or at most, with a "can negate durability with Existence Erasure" in the tier/AP section.
For now, I'll leave the thread closed, since I'd like to get a quick staff view on this topic before re-opening.
