Hey, really, it's not a major deal. If you want to play a pixie, by all means, play a pixie. I don't want your dislike of your character to be a reason why we lose a good player. History has shown that when Shayuri makes an unscheduled exit from one of my games, the end is very near. [Ok, so that game had more problems that you can shake a jumpdrive at, but who's counting?]
Truthfully, I had this fully realized concept for an Eladrin party on a mission, but a few nights of sleep, and that sucker evaporated. Gone. Like smoke. So, maybe it'll come back to me, but it can be adapted, and switching from Eladrin to Fey is easy enough. If you want to be the only Pixie, we can talk about that. If you want to be the only non-Eladrin, well, that's tougher, because how can I really say 'no' to someone else when I've already said 'yes' to you? But if everyone else is gung-ho rabid to play Eladrin then you'll have your cake and eat it, too.
