Is there any chance of being able to use a ground mount as appearance with a flying mount equipped for stats, i.e. the use of a ground mount in the appearance slot prevents flight? I'm not suggesting existing ground mounts should fly! I've picked up any number of very nice ground mounts - purchased or quest rewards - over the years and very rarely use them. There are so many zones where flight is not allowed anyway, it would be a welcome change to be able to bring out some old favourites from the stable (without stats taking a major hit) - especially the good ole' Sootfoot Lava Cow!
It'd be nice if we could at least when it was on the ground. =( I've got a ton as well over the years. And gliders, gliders really shouldn't be an issue over flyers.
