Unlike some other draenei and blood elves, I'm not 60 yet. I hit 40 last night on my Draenei Shaman, and immediately picked up the mount and converted to mail gear. Then, a feeling of emptiness came over me. I was puzzled. I've leveled up before through Azeroth, this Shaman will be my 7th trip to 60 (and now beyond), and I really do enjoy leveling. What's hit me though is a feeling that I'm stuck in the same old content.
It's not that I don't love Azeroth, I really do. It's been my home away from home for almost 3 years now. It's just that while I'm grinding away through levels in the "old country", all my guildies are out in the Outlands having fun and getting drool-worthy gear from mobs I've never heard of. Yes, I have some awesome company in the leveling grind (frequent commenter Skew is a good friend and guildie) as we both get our shamans raid-ready, but really, there's no sense of awe and exploration in Azeroth anymore.
Would Blizzard have done better to implement a bit more mid-level content in the expansion? Levels 1 through 20 were fantastic on Azuremyst and Bloodmyst isles, and I've heard the Blood Elf content is just as fantastic. There's something particularly cool at the end of the Bloodmyst quest series that leaves a player feeling good about the world and their place in it. And then you head into the rest of Azeroth.
