Sleipnir Useless in Heavensward?

[LordHadi]

So almost all mounts can fly now, Chocobos, Ahriman and Primal ponies.. except for the mount we payed 16.8 EUR for?
This is not a request for making it fly, but maybe add more to it like customising it or make it faster on land or a special feature maybe?

EDIT: I'm not complaining about the money paid, I'm just adding an info it also had a price and now it's just less useful in HW. This thread is open for suggestion whether there will be any extra features for Sleipnir (or any other land mount) but everyone here turned it into whether a Sleipnir can fly or not. It was mentioned in one of the threads that they will be adding an emote for Sleipnir and can't remember if they mentioned anything about dying it, but no news have been released.
