Sorry, but I'm going to have to agree with Al's second comment in this thread.

I FULLY recognize the hard work Blizard put in to the revamp (even if I didn't always like some of the choices they made), but that revamp was NOT part of the expansion. We didn't pay $30-60 for the revamp -- the revamp was available to EVERYONE before the expansion even hit. The revamp was a massive content update for everyone, including people who were playing free-trials. I'd argue that our monthly subscription paid for that. And, to be fair, they DIDN'T completely overhaul the entire 1-60 game-world (Arathi Highland and Silithus and Deadwind Pass leap immediately to mind, as does the lack of phasing in Dustwallow). What they DID get to was frequently amazing, but that's not what we were paying for when we bought "Cataclysm".

The expansion we were given, the expansion we PAID for, was lackluster. Five levels of content (which I, as a super-casual player, finished in less than two months), five new zones (one wasted for the Alliance and the other wasted on a giant neutral pop-culture reference), two recycled Zul dungeons, etc. Blizzard even admitted that the expansion we paid for had several points which were slapdash (the Worgen post-Gilneas experience and the Alliance intro to Twilight Highlands, for instance) and decided they didn't need to give us what we were promised -- ie: what they'd sold us -- in the form of the Abyssal Maw/Neptulon's fate because they didn't feel like working on it anymore. They forgot to explain why Alexstrazsa and Nozdormu were suddenly present for Thrall's Quest, even though one was supposed to be near-death and convalescing and the other missing for years (seriously, NO-ONE in that scene reacts to Nozdormu's SUDDEN AND UNEXPLAINED return?), then treated everyone to a long quest about how awesome Thrall was and how we should all love him and how he's the best thing since sliced bread and oh goodie we got to witness his wedding! But they didn't bother to explain why Alliance characters should care about any of this.

Wrath & BC had their problems, but those expansions were both breathtaking in scope and execution. "Cataclysm" as an expansion -- "Cataclysm" as a product sold to us and distinct from the 1-60 universal free update -- was a huge disappointment.
