No, it didn't. The original wow, before any experience changes required the exact same zones, unless you were instance grinding. At higher levels it was even WORSE. Considering half the now present zones weren't even populated until later on or during patches.
TONS of zones were DEAD; devoid of any quests whatsoever, and in the event you did get a quest there (azshara for instance) it was from a major city.
1 path for horde and 1 for alliance, very few contested zones had multiple faction hubs -- perhaps hillsbrad and arathi were exceptions.
On top of that, nothing was streamlined at all; quests would require you to fly from Tanaris to Darnasuss -- that's like a 15 minute flight, AND back to turn in some quests. It was absolutely nuts.
And, as far as end game went; 2 raids -- Molten core and onyxia -- and yeah, I guess you could count UBRS, so 3. And you had the L60 stuff. Other games have more content at launch then wow ever did.
4 dungeons, 3 raids. Wow. So much there.
