Oh yes.
When my hunter used to be accompanied by pets, I named my [pet]Dun Morogh Cub[/pet] and [pet]White Tickbird Hatchling[/pet] after her two helpers. The other pets were a Northrend wyrm and a Cata wasp, so no equivalents for them --
therefore, I started to wonder how these ones would look like as companions.
With Legion prepatch all old bears, including the tamed ones, were switched to a new model.
But… not a Dun Morogh Cub. They no longer match.
Not like this matters anymore because of a Lone Wolf MM; however, my other plan was to tame undead/white versions of former companions so I could pretend they were murdered with changes applied to the hunter class. This doesn't seem very possible anyway, so at least I can use a Spirit Wand on the lil' equivalents.
I don't have enough patience to collect mounts.
