Its definitely two issues that I can tell. The first issue of animation is minor, but any pet that has a proper ground/walking animation should use that even as animal companion. The rocs are a great example. As the primary pet, they use the ground/walking animation. As companion, they are use flying animation. Its odd that it doesnt affect every pet that has both sets of animations. Legion hippogryphs are affected, but the wolfhawks arent. Obviously this doesnt apply to things like moths that dont have a ground animation. So yeah its minor, but I find it annoying
The second issue is worse though. The floaty pets arent grounded, they can actually fly and I can't imagine that is suddenly intended. This is different compared to a moth or bird of prey, while they use the flying animation, they are firmly grounded and must follow ground pathing rules. These floaty bois break all the pathing rules.
As long as its known is all I'm concerned about. My floaty/swimmy Blaithe will stay stabled for now.
