I have to disagree with you, Drak.

For low-level zones, I didn't mind the linearity of the quest structuring. If you really get bored with a series, you could just go to a different zone of the same level- you'll outlevel both of them soon enough. I think cohesiveness, progression and fun within a zone is worth it.

I can sort of see your point for someplace like Uldum, if you've somehow depleted Stonecore and aren't allowed into the Twilight Highlands, but that's almost impossible. Call me a heathen, but I didn't find the Harrison Jones portion to be very compelling. I saved the kittytaurs and skipped off to the eastern kingdoms. If you don't like questing, you simply don't like questing and should PvP or dungeon your way to 85 instead.

I'd also like to add that if you're questing through a zone just to get a particular item, I personally think that you're "doing it wrong." To be fair, several of my friends did exactly that to gear up after they hit 85, so I suppose you should take that with a grain of salt.
