So not expecting much, but I wanted some clarification here.
According to this thread by the Community Manager:
Dire Wolves and regular wolves are listed seperately, With Dire Wolves needing a Tier 3 pen, while normal wolves only need a Tier 2 pen.
But I just tested this out on Testlive, got a Dire wolf cub (listed as “Frostwolf cub” in the admin panel. And it appears the Dire Wolf is more like the White Tiger. A “Greater” version of the normal pet (in this case wolf).
When I was raising the frostwolf cub, it listed its adult form as a wolf. Sure enough, when I finally got the adult pet, it is list as “Greater Wolf”. rather then direwolf.
Obviously, I got the animal I wanted, but I would be great if there was some clarification if the Dire Wolf was intended to be a Greater version of the normal wolf, or if like the guide I listed states, it is suppose to be its own pet.
