Choosing a new interpretation and trying to see if that interpretation fits with the statements is NOT going by what the statements imply themselves. You are ADDING inferences there. Absolutely nothing implies that they're going to destroy one universe and then travel to another one, or have their power from fighting in that one destroyed universe travel a massive, unquantifiable distance to and from the other one. You're trying to make your idea fit so you can preserve a rating instead of letting the statements and verse generate the rating itself. That's pretty bad.
And I don't even understand how 5D not just for Dragon Ball, but for any and everyone who has done 2-C feats by having their power or bodies exist and move on a 5D axis is wank. If anything, it means our standards for the tiering need to be changed, or "5D power for almost every 2-C character who didn't somehow destroy universal spacetimes without traveling through 5D space or across a 5D axis" is the rule.
And the ruling you're thinking of is wrong Rash. Donttalk himself said that universes are embedded into 5D space, and the TIER DESCRIPTION says
Low Multiverse level: Characters who can destroy and/or create up to 1000 universal space-time continuums. The power difference between Low 2-C and 2-C characters is not possible to exactly quantify, given that the latter category has to breach the distance between universes along a 5-dimensional axis.
Unless you can somehow explain to me that a 2D drawing can walk around in 3D space and not have 3 Dimensions, as in they are 3D, then power or energy or attacks or beings that can move on a 5D axis are 5D. Point blank. PERIOD.
I know we can handwave 3D beings with High Dimensional power and immeasurable speed beyond time and shit, but we can't do the same with power or else the tier system loses its meaning. And we have never done that before. And it would also downgrade every actual higher dimensional being who are stronger than High 3-A characters for the simple fact that they're higher dimensional, and just as our infinite 3D size could never even be comparable to their 4D size, the same applies to power. If we reject this, then we reject the tier system as a whole.
Goku and Zeno and whoever existing in a void like that Rash is debatable in terms of evidence of them MOVING on a 5D axis, but that being "true" only makes them stronger and faster than what you're arguing for. So go ahead and vote for an upgrade, since you want to throw out any amount of evidence to prove any point you can even at the detriment to your own position. And, I don't even think I agree with the evidence you're presenting there— in so far as that evidence supports your claim.
The low ball isn't always the most rational interpretation even when things are vague, but I will grant you the idea that low-balling in response to a lack of information is better than nothing or adding information to suit your idea. We should always take the safest interpretation that requires the least amount of assumptions, and the assumptions we do take have to have solid evidence or reasoning behind them.
Problem though. Your low ball comes from adding information, taking extra assumptions, and basing those assumptions with at best weak reasoning.
The scene you are given has ABSOLUTELY no indication that the destruction of two universes was going to be sequential. While it doesn't EXPLICITLY state that the universes are gonna be wiped out simultaneously iirc, that assumption is the simpler, easier to explain and account for version that has more implications backing it up, as Whis and Vados stopped them before anything could really be done— implying with their expediency, efficiency, and overall haste that there was a REASON to rush and stop them when they did, which gives weight to the idea that their fight might have immediate and drastic consequences— that the consequences the Angels outline might be immediate and drastic. There's also them fighting over the baseball game (which is also between the same two characters who were previously asked to not fight or the universes die) resembles another scene in the franchise where a character was going to chain reaction collapse an entire space time, meaning it's not out of the realms of possibility that they MIGHT destroy it all at once. And while we DON'T 100% know for sure that this is the case, all this implication on top of the idea that every other interpretation to have the ratings be different or the feat be accomplished differently rely on weaker inferences based on very little than the idea that it's "possible" since there's nothing saying it wasn't going to be done or doable in the way you argue.
So, not only is your interpretation of the feat supported by the weasely sneaky loophole of saying "they didn't say it WOULDN'T happen like this" which is blatantly assuming more than you're given, but your explanation for how that could even be done is bafflingly more complex than anything implied. What part of two gods fighting can nuke both of the universes implies that they are going to SOMEHOW nuke one, and then SOMEHOW get to the other without having to either travel at speeds they've never done before or demonstrate feats that could be POTENTIALLY HIGHER than the basic assumptions we're making would. How the hell are they gonna nuke two universes with gaps in distance at least far greater than anything they have ever traversed with Ki blasts or movement speed. And doing so might be 5D because those blasts might need a 5D axis to travel along.
We usually assume the end result of the destruction of one universe is an empty void, rather than 5D space, which is why I disagree with that Future Trunks stuff Rash. And that alone isn't enough to determine if they can move in 5D axis or their blasts can or not.
I think we should change the definition of 2-A, because it seems more consistent that being above Low 2-C requires interactions with 5D axis, making things 5D because you can't travel on a dimensional axis without having or existing on that dimensional axis. This way, we get 2-C characters all over the wiki stating just as they are, solve the unquantifiable "no multiplier" gap between Low 2-C and 2-C by stating that the gap requires more than infinite 4D power by virtue of feats typically needing to be done through 5D axis stuff, and not have 2-A dragon ball because that's way out there.
