Rarity is based on factual numbers.
Demand is based on feelings.
I don't look at it as pets "BECAME" a different rarity.
The number of pets relative to the number of users did not change.
Pets did not become any more common or rarer. They just fall in a rarity category.
For example: If a pet was 1 in 10,000, it's STILL 1 in 10,000. Instead of being lumped in with pets that are 1 in 5000 or 1 in 15,000, they are more precisely identified in a group closer to 1 in 10,000.

Seeing so many pets became “OMG so rare” is crazy. Now it will be impossible to obtain many of them. To me it seems like newer pets went down even more in rarity, older pets went up. One of my very rares turned to “OMG so rare” (white Malk dragon) and personally I still can’t say that this pet is rare enough to be called an “omg so rare” and is equal to the pps blue Malk dragon, for example. And now they are in the same group.
(Surprised to see raven dog just as an extremely rare)
