Blizzard likes to talk about their "iterative" process, meaning they make many small improvements over time to produce the best possible result. In the case of the lackluster patch 2.2, players were disappointed that more was not done. With the game's subscriptions still skyrocketing, Blizzard felt pressure to deliver a major dose of new content and improvements.
In November 2007, Blizzard answered the bell and unleashed an iteration that reshaped the game from top to bottom. Players of every level experienced sweeping changes to their play experience -- many of which are so integral now that it's hard to believe we played without them for so long. If you ask players about patch 2.3, they'll call it the "ZA patch." Zul'Aman was a great raid, but 2.3 offered so much more than that.
