I don't know who asked for this feature, but please make an option to disable it.
My horse frequently dies because it teleports in the middle of a spot with mobs, or the least is that it gets stuck somewhere and I have to call it, which I would do anyways before the teleportation system.

I had no problem managing my horse while questing, and with this new addition it makes managing my horse way more difficult and tedious.

I hope they let me disable this before the new expansion launches. Not playing this with my horse on my effin head all the time.

Yep, this is an obnoxious "feature" and one that clearly wasn't tested all that thoroughly. At the very least let us disable it in options, although so you don't leave a bad impresson on new players because their horse keeps getting teleported into packs of mobs and murdered, maybe best to just disable it altogether.
