I like some changes and some not. The most bugging thing to me is the new corvid model that has nothing to do with corvids.
And there would be one of each species that would keep the old skin. Some creatures deep from the classic game. Or a pack of new pets with old skins, perhaps from Timewalking or Caverns of Time.
Or Emerald Dream, to keep it within expansion and still within the lore a bit!
(It used to be regarded as an alternate world, where no species was tamed and shaped by people, right?)
