Personally, I'm excited about the one particular thing that most people have not yet mentioned, the secondary skill, Archaeology. I feel that this will be a very useful skill in the long-run, especially with the rumors of this so called "Re-Forging" going around. but really, I'm also excited about mainly just another expansion coming out. Seeing as I started late in Wow, about patch 3.1 or slightly below, I have yet to catch up in terms of gear, raid etc. I want to use this opportunity to get ahead, to feel useful in the matters of helping others upon release with my knowledge of the beta(even though I have yet to find out how it really will be). Mainly, I'm just excited about a new start, a chance to be more important, not just a under-geared starter.
