I would put powdered peaks in the d tier (mainly because it’s the smallest world with only two areas), peculia and nimbus and otherworld in the c tier, galados isle and karkaton in the b tier, realm of the fey in a tier, and greenhorne, the sky scraper and new lumos in s tier (but that’s just my opinion). i also wouldn’t consider traveler’s hub a world, mainly because you don’t do any fighting there.
