Leveling way to fast

So yea, it's pretty sad.

Are you personally playing a level capped character? Have you experienced both the Vashj'ir and Mount Hyjal's questing experience? Have you created a worgen and a goblin, and seen what those experiences have to offer? Have you experienced the new and revamped zones scattered throughout Azeroth via multiple 'leveling paths'? Perhaps your Archaeology skill is maxed? It might be sad if all the new content was exhausted in a couple of days. Fortunately, that's very, very far from the case.

There is much, much more to World of Warcraft: Cataclysm than simply racing to 85. If that's your goal, fine, but I would argue that doing so intentionally skips much of what this frankly amazing expansion has to offer. Personally, I've never had so much fun questing, exploring and just playing, period; whether at level 8 or 80. I look forward to the new challenges that await at the level cap too.

Ultimately, fun is subjective. I hope you find the experiences that bring a smile to your face, in the expansion. Keeping an open mind can help.
