Upgrade from a white horse to a Pegasus.
Flying mounts are common in mmorpg games especially when the map gets so big. Firstly, horses are pretty much obsolete, which is sad because it’s a neat aspect of the game, but with people able to fly at lightning speed and teleport scrolls, they aren’t too useful past the early game. Additionally, horses are buggy when traversing the terrain (lots of lag back), making for a frustrating experience.
However implemented, some kind of next tier to horses seems like a logical step to the horse mechanic; I believe that makes flight the most logical option. You can obviously determine how powerful these would be and whether it would be the same upgrade mechanic or some new lore involved method with fruma coming (just something that involves needing a white horse).
Just thought this would be a fun breath of life to a fun but dead mechanic.
