This was released roughly 2 years after the initial vanilla wow powerleveling was released. For a 2 year development cycle, we also had several unfinished/finished_but_not_released content patches about wow powerleveling.  They include:

With the exception of Sunwell Plateau, both ZulAman & Black Temple were physically finished, but not polished. The standard explainations of what might have been needed to have been done apply here as well. It is important to note, that during this time, Blizzard has come out and stated that they were employing 120 people who were working directly on WoW. This number does not factor in GMs or anything of that ilk, just the various developers. This naturally did not sit very well with me, but I will cover that later about wow powerleveling.

Now, looking at things, we need to put things in perspective, to help give everything a bit more weight on the subject of "Time Invested vs. Content Delivered". Simple math would assume that

Simple math dictates that we should be getting roughly 40% of the original WoW in return for that amount of time, correct? Most of us originally paid 49.99$ for the vanilla WoW and later paid 39.99$ for it is first expansion to get wow powerleveling, but I will not gripe too much about the cost to purchase. Many folks feel that what we received was slightly under that 40% mark, but the overall delivery of content was of an acceptable level to get wow powerleveling, due to various time sinks built into the expansion itself.

Now, we are sitting at the launch of Wrath of the Lich King. Again, this is another 2 year development cycle expansion pack for WoW and again, we should be getting roughly 40% of vanilla WoWs original content. But something odd happened on the way to the barn, we lost about a third of what we needed to be getting on launch! I was one of the first bunches of people to say "Is this it?"
