Here's another little mini rant on scaling:
You don't like scaling because it presents a more accurate way to judge the characters than comics. It is something largely not present in comics.
It is entirely a storytelling device in that newer is usually better, but it allows them to ramp up the threat without ramping up the damage. Characters don't have to destroy large landmasses with a flick, yet we know they are vastly more powerful than that. Characters are always growing to a point where they don't need statements to know how they measure up against the last bad guy, we just know.
Again, this is largely missing in comics. How much stronger is Superman than he was during the Byrne era? You don't know, you have no idea. You can't with any reasonable idea even begin to form an accurate conclusion to that question. However, Dragonball fans can put you in the ballpark of how much more powerful these characters are than they were, or the previous baddie. Majin Buu for example, is at least 4 times stronger than Cell. Beerus is at least 100 times stronger than SSG Goku. SS Goku on Namek was a couple hundred times stronger than a planet destroyer. Etc.
Thus it is natural for you to want to ignore that, because it doesn't effect comics to the same degree as Dragonball (it absolutely does however, as evidenced by you using Doomsday as an example). So naturally you want to rule it out. Dragonball doesn't work like that however. Power scaling like it or not, is an integral part of the series, and it gives the series a degree of accuracy as opposed to everything being Superman level but not quite.
Give me some time and I can ballpark Goku's power level anywhere in the entire series, and significant things he did at important power levels. I can explain why this means something. Can you explain why Superman can do Y but can't defeat X? Doubt it, yet you think that PIS should be applicable but power scaling shouldn't? 😂
That you can scale a Superman feat where Spectre can't hurt him (when was this), or where Doomsday is impressive? Why are both of those things impressive btw? Oh right, scaling off of Spectre's feats and scaling off of Superman's feats to give to Doomsday.
Do Dragonball characters need scaling? Maybe, maybe not. What I do know however, is that it's a huge part of Dragonball and it makes zero sense not to count it in lieu of other things here.
