New Friend Recruit mount size

Hello, a friend of mine got the mount (Managarm) today and I must say it looks rather small for a hyur, I wouldn't want to see how small it will look on a roegardyn.

Here is an image showing Fenrir next to Managarm:

I do not know if the reason for its size is behind some lore, but if that is the case, it would be nice if it grew just a little more, at least 25-50% more than what it is now, rather than double the amount which seems to be about the difference between the 2 mounts.
