Fine.
I'll tell you that from
since the very beginning I am advocating for only a "possibly 2-A", I never said it should be Bill's base tier, but 2-A has absolutely to get in there, given I think the narrative of the show definitely tells that Bill is more than just something Universal to be honest. But besides, let me start.
Honestly... I think you're kinda overthinking this too much. A 2-A will always be logically a threat to the universe, as it
has to get involved in its destruction. Basically how the country is in danger if there's a planet buster in short, this is pretty much the same. None of these really are a big nope to Ford's claim about Bill being 2-A, as it's not like we have to be constantly spoonfed with "Bill will destroy the multiverse" constantly. We just got a statement of Bill being a threat to the multiverse + Time Baby saying that Bill will blow up the fabric of existence,
with Time being absolutely related to the infinite timelines, saying that the "fabric of existence" is limited to a single timeline is just dumb and taking a veeeeeeery weird interpretation. Let's take Dragon Ball Heroes/Xenoverse for example, the flow of time is something that exists across all the 2-A multiverse (as seen in the AP section for these
two characters), the same is with Gravity Falls, where the Time Baby is the ruler of time, thus it would be logically be reffering to the multiverse here.
Plus Blendin was blatantly wrong. Bill did never destroy anything, he was merely panicking as he literally just ran away to the future and wrote stuff as in "he used my body for his plans of time travelling and destroy the universe!", but the latter never happened. He simply was wrong, and that's it.
Going again to Dragon Ball Xenoverse, the Nightmare Realm works exactly the same as the Crack of Time. If you see
Mira's profile in the AP part, you'd see that we currently accept that Mira blowing up the CoT is 2-A, as it has to be 2-A sized at absolute least because of it being between all the timelines. After all, the entire reason why Low 2-C is so weaker than even baseline 2-C to the point that even an infinite multiplier of Low 2-C won't bring you to the the next tier is because of the distance between universes that makes the trick. It's why 2-C is a bigger deal, coz of it being physically bigger than 2-C right because of this range. So how would a Low 2-C sized realm be able to connect all the universes of the 2-A thing? Because it has to cover also the space between universes that makes 2-C greater than Low 2-C, let alone if you take it with infinitely more universes.
Alright, so this is just... stupid. It's a thing that happens all the time in fiction, with multiple characters seeing/perceiving infinite stuff despite having finite sensory, as otherwise we'd literally have to axe away over half of the High 3-A/2-A cosmologies here because of the characters describing those infinite sized realms being humans or still non-omniscient beings with finite perception.
This is literally you enforcing your own standard on how things work on this wiki. I don't know how this argument is even acceptable, given that you're essentially saying "how could Ford know this" when it's something that happens in literally every franchise ever?
To be fair, Bill was only just shocked due to him not being able to get past the barrier (given it's an Anti-Bill thing, literally), but then he found the Shacktron's weakness and dealt with it in a matter of few minutes. Yeah, he didn't one-shot, but this is fiction, we don't expect AP gaps to be potrayed accurately (otherwise for example Tier 2s wouldn't be able to hold back against Tier 3 and below because of them being literal infinities above them), plus it is indeed PIS as the narrative demanded Ford to build that circle and explain all of it. Obviously Stanley screwed it up making it meaningless to the end, but it was still a necessary thing to make that part of the story work.
Besides,
I've calculated the Standford's stuff through size (as 4-A is just nonsense and even breaks our rules of Large Size Calculations) and I've got some neat stuff for the AP, LS and speed.
I think Bill should scale to those even without the size, as there's no reason why he should be inferior to the things he grants power to, as he literally is the one granting these stats in the 1st place.
But for his Tier, I think the thing should be "
High 3-A, possibly
2-A", the portal shaking the NR is High 3-A at the absolute minimum indeed, with Bill being stated that he can destroy the universe multiple times and he claimed that he can give infinite power and has it himself anyways twice.
Possinly 2-A comes from the Time Baby's statement (plus what the details I've provided above) + Bill having indeed 2-A range for the portal, and he has still the intention of making the reality itself lawless, given his whole plan was to spill the NR in the "normal" dimensions, and Ford saying he is a threat right because of this. If the NR is something between all the universes, with the portal he scales from shaking all of it, then you can indeed argue that being 2-A as well.
Besides, I think I am done writing here, and I guess I'll just leave the staff to comment on my take.
EDIT: Apparentely Low 2-C is also argued as his base tier as Time Baby's statement would logically involve time too, given he's the ruler of space-time itself.
I don't mind it being its base tier either, I am neutral towards agreeing for it.
