I'll be honest; I wrote this week's column purely for brainless fun. You won't learn anything (not that you do normally), there are no insights to be gained (not that there are normally) and I don't have any new Cataclysm alpha information. I am very sorry to anyone who came here looking for a solid, informative column, and if you wish to excoriate me in the comments then I encourage you to do so.
Anyway. When it comes to druids, the deal with race choice is that you don't really have any. If you play Alliance, you have to play a night elf; if you play Horde, you have to play a tauren. We're the most race-restricted class in the game, and even in Cataclysm, that's not really going to change.
Some of you might recall a bug from a little while back that allowed you to model-swap between characters on the same realm by "choosing" two of them at once. I'm pretty sure it's been fixed now, so I wouldn't bother trying it if I were you, but I had lot of fun swapping non-druid races into our various tier sets and wondering what it might have been like to play them. I screenshotted like a maniac while doing so and then set them aside for a future column whenever I felt like doing something just for fun. That would be today.
