The Tier 1 Stables in the Garrison has the following perk:
Also allows you to remain mounted while interacting with objects in outdoor Draenor zones.
This is pretty great if you're doing a lot of questing. I'm working on Loremaster of Kalimdor and it would be wonderful to have this feature there. Is there any way to get a similar effect to the Stables effect outside of Draenor?
