Dungeoning or Questing to 85?

[Gogetaex]

I've heard that dungeoning until level 82, then jumping into Deepholme is faster than questing in Hyjal to level 82. Is this true or not?

That would of course depend on how fast your group finishes a dungeon...if you're looking at running it with friends, I imagine it can be qutie quick. If you're just doing random lfd groups, expect it to be a slow painful process.
