When BC first came out, most people went right in outlands, while some people took up JC, some people rolled the new races, and some just explored the new cities. Now when WOTLK comes out, what will people do? Personally, I think I might find the DK quest starter (wherever that is) and unlock the DK.
Explore. I tend to like to scout everything out as quickly as possible not only because I enjoy doing it, but so that I can grab any flight paths I might need or to find alternative areas to level in that aren't highly populated right off.
I'd ask that everyone please keep it on topic and not start discussing other games. If you wish to do that, the off-topic forums will be the best place. Thanks.
