Riiiiight. Because, ten new levels to advance through, seven new zones on a new planet, a new profession with huge potential for powering yourself up, two new races, giving Alli Shammies and Horde Pallies, reducing the max raid size to 25, adding a World PvP objective in every single Outland zone - including a capturable town, flying mounts, however many new quests, instances, mobs, and items there are going to be, none of that is significant.
Just like any other expansion out there really, as per what I mean. The changes and improvments to WoW are fair, but nothing to get excited over. I felth that WoW brought something special when it opened, and it had a fair sparkle to it. After a few years of Mythic like promices, some let downs others adequate, I have just come to the point where somthing exciting - not effective - would have to be added. Prehaps I am just WoW'ed out- and have been for some time.

Also, from a per patch prespective of what they have added over the years, it is not overly significant.
