I wasn't quite sure how I would portray "fast" in-game. There are a lot of things that can be done fast...questing, crafting, flying, old raid/dungeon running...then it dawned on me.
One of my favorite quests in Pandaria has some of those Warlock type teleporter gizmo thingies around the perimmiter of a room. The quest boss you fight uses them to bounce around the room. You can click on them as well and follow in his footsteps "fast". (The quest is "The Fall of Ga'trul" for Alliance only)
