In Skyrim, I literally avoided horses. At first I tried to use mounts, but I had a few problems. My main problem was that they were dumber than oblivion horses. You could not back up directly, which could leave you to go over cliffs. Also, there was no first person view. Another problem I had, which was my personal hangup, was that I was passing up a lot of ingredients when mounted.
I decided early on that I would not buy a mount in ESO. Then they announced that mounts can help carry stuff. So, now I was wondering if my mount would follow me when I walked. I still do not want to mount up on my horse, but I do want a pack mule.
I was even hoping we could buy a cart for our mounts. Extra carry space would be nice.
I hope there is a feature that makes your mount follow you(optional), so you don't have to mount your horse, you just have one with you when you travel.
