I completely agree, turn the magical waypoints into fast travel, just the way it was done in BGII.
Also, I love the way they made the Underdark, and think it is one of their greatest achievements so far. But it makes no sense whatsoever that such an eerie, unreachable place should have the same waypoints, or even fast travel back to the surface option.
The game makes it hard to get there, so why would it be so easy to come back?
I'd much prefer it to basically be stuck in the Underdark once we get there (with maybe a warning), or be able to get back to the surface only through the stairs to Gut's chambers or the portal to Ethel's place.
Also, as has been mentioned, camp should NOT be available in the Underdark.
Unlike BG2, the Underdark here seems to be a place like any other because of the waypoint / camp system. Soooo immersion-breaking
