How would that work? Do all 3-C became 5-Bs or the other way around?
In my view 5-Bs are the strongest level of characters that are "stuck" on earth in the sense that they spent most of their time there. Then 4-C up to 3-C would be cosmic characters, those who often travel to other planets, the likes of Nova, Quasar, Captain Marvel ect then you got the heralds. I think it makes more sense than low mid and high heralds.
Honestly I don't know. Like there definitely is a significant difference in power between the likes of The Thing and of Silver Surfer, and of Iron Man and Blue Marvel, but I don't know how big it is. Like Super Skrull can fight Silver Surfer, but Super Skrull is also shown to be on Thing's level. Iron Man has defeated characters like Terrax and Ulik.
At the very least, I think that the cosmic characters should all be merged into the same tier. Silver Surfer, Gladiator, Quasar, Nova, Blue Marvel, Hyperion, etc. Tbh though I'm a bit iffy on 3-C now. A solid chunk of the 3-C feats we have are from Thor or Hercules, who should not be scaled to since they are gods. Silver Surfer does have some good 3-C feats, but I'm wondering if the 4-B range is more consistent? Idk.
I think you might be right about earthbound characters being on a lower level that the cosmic heavy hitters actually, looking again at some of my notes.
Where do you think this leaves earth-based "teambusters" like Count Nefaria and Graviton? Both are sometimes implied in their old stories to be stronger than peak and Thor and Hulk, which is a problem as peak Thor and Hulk are both 1-A. I have to say, Thor is posing quite the problem because he has a ton of Tier 1 feats, but is basically the only one to have those feats.
Maybe we could end up with something like:
Earth High Tiers:
5-B (I think these characters being Planet level at least is extremely consistent)
Herald Tiers:
3-C (or maybe 4-B if we downgrade)
God Tiers:
1-A
Alternatively, since some of those Earth High Tiers have on occasion held their own against, or even outright defeated, Herald Tiers,, we could have just:
High Tiers and Herald Tiers:
3-C
God Tiers:
1-A
Or:
High Tiers: At most
3-C
Herald Tiers:
3-C
God Tiers
1-A
Or, the "**** it we ball" option:
High Tiers, Herald Tiers, and Gods:
1-A
