This idea of a "first character" is actually especially interesting to me, as just yesterday my very first character dinged level 60. As I said on the podcast the other day, I'm going back to play the Night Elf Hunter (yeah, yeah-- I was young and impetuous, and I heard Hunter was a good solo class) I started playing the game with, and take it all the way to level 70, and then 80 when Wrath comes out. In some way, I see it as finishing what I started way back when. And after all this time playing something different in game (Horde, obviously, and classes besides Hunter-- Warrior, Shaman, Rogue, Priest), it's been extremely interesting to go back to the beginning. And seeing Outland (and eventually Northrend) through the eyes of the first character I've ever played promises to be a trip. I feel like I'm rediscovering this game I've played so much of already yet again.
What happened to the first character you ever started? You didn't delete them, did you? Were you able to get them all the way to 70? And when the next expansion comes out, will you take them further?
