Uh... This topic is lacking context.
You want more mounts while mounts are obsolete.
What'cha need Search Function for...
Uh... Party banter to you too.
Facts straight though.
The mounts do have a few uses in the game.
Speaking from personal experience.
You may need a mount to get through old terrain to an unexplored area of the land.
...As in you do not fast travel as level 20 through level 5 content to a camp you've never been to.
And it is redundant to walk on foot since gathering materials or possible hostile's are low level.
You may wish to ride a mount to the borders of a town/village/camp feeling like a proper Inquisitor. Why not. It is a Roleplaying game.
On the other hand. It would sound better to disable the mounts entirely rather than go and revamp the whole mount-system.
