Oh, I quite agree, except for the "Or".
Why would Hussie decide that Gamzee reached godhood but never leveled up after that? I say: Because that way Gamzee doesn't have the Gift of Gab, and thus we don't know that he's god tier.
There could theoretically be a different basis for that decision, but I doubt it.
