I mean, if blizzard was being completely honest then it’s coming soon . . . ish . . . don’t expect anything silly as a charger though like ponies or dogs or whatever meme answer some folk are thinking (seriously gnomes aren’t THAT small). If anything the gnome paladins mount will be some kind of gilded mechanostrider with whatever paladin order blizzard comes up with’s sigil on it (either the silver hand or some kind of new gnomish holy order . . . my money’s on the former).
As an aside . . . do Shetland ponies even exist in WoW? Do Clydesdales? What breed of horse IS the one all the humans use? Are their more then one breed or are they all “generic fantasy medieval Europe human charger” breed? What about dog and cat breeds!?!? The people have a right to know!
