It would've been cool if the DLCs had gone a different route and we get one every 6 months with the same continental themes but expanded more, like for example:
Bolded Species are the brand new ones, a lot of this is shuffling around ones we have gotten from packs

Then after that into 2023 I would do just species packs like JWE2 filling out the rest of what we missed:
March 2023: High Climbers Species Pack; 4 species including Lar Gibbon, South American Coati, Dall Sheep and Sun Bear.

December 2023 (Send off): 4 more animals that would fill the last spots of the roster that I cant think of right now.
