Realistically, drow wouldn't wander around the surface freely and in plain sight, unless they are very stupid or I suppose if they trust the laws will be upheld even with them around (even then, it's unlikely). However, if there's no place for these players to go, then I can understand why they are hanging around the cities.
I won't discuss the PvP issue, because I'm not sure exactly how things work on this server yet. As far as drow being around in general, though, I suggest giving them a small place to go (unless there already is an underdark on this server). I'd make a drow for this server if you did, that's for sure. ;o) I am rather biased, though, but I love drow RP.
Anyway, just a little suggestion; could create a nice little conflict between factions, and hopefully create more RP (though unfortunately I suppose it could just end up causing more PvP). ::shrugs::
