To put it very shortly and simply:
ICly, my drow wouldn't like to visit the top. Besides, if she truly does need her spell components, I can always ask some drow to ask someone from Skullport for spell components.
ICly again, on another character, I have seen halfdrow being sent up as merchants/informers for the drow stuck in the Underdark.
On the whole, I think the way it is now is good. There are thousands of opportunities for RP, it all depends on whether you think of it or not. Yes, it gets boring sometimes because there is no one online, but whenever I type 'who', I do keep a lookout for drow online so I can possibly log on and strike up some fun RP. This way, I play my part.
I strongly feel that the Underdark should not be such an easily accessible place to the surface beings (which is what having surface drow implies), and vice versa.
I agree with what Mariela said, something along the lines of having a nice quiet, safe place all to ourselves, and I really do like it that way. This is the only character that I have had that lives in a place so full of culture and beings of ONLY one race. It adds to the effect.
My point is, I feel that things should stay the way they are now. Even though I've had my drow character for less than a month, I've received a considerable amount of help and RP there. Much more than I expected, anyhow.
I suppose, if you want a surface drow, go ahead and apply for it, but I don't think they should have daylight adaptation, still. It's not in their nature, is it?
This is an RP mud. To me, if you want to create a character, you shouldn't be looking at how powerful it can be (unless you have some sort of big RP in mind that you HAVE to be powerful for). Instead, you should be looking at how much you are willing to sacrifice for this SURFACE drow. That means accepting all penalties to being on the surface.
