No there shouldn't be anything else to do. Just make sure you select the BG you are running and it should work. It is a little buggy in Arathi Basin for me though. Upon entering it goes further into the house instead of running outside. It is trying to run to the graveyard waypoint but doesn't run outside first. It also doesn't mount after leaving the cave in Alterac Valley and if you die and respawn at the cave, it gets stuck.
