So you won't be lonely...
I mean
Fix the second lift/elevator?
(bad ideas I know)
Better question: Are they really points of intersection for knights traveling further into clockworks? I think it would be sort of cool to run into some other lone traveler who happen to get there moments before you through the same gate instead of someone just joining a party to end up there. And if they wish to depart, is it possible to make the lift/elevator on the left act similar to the ones in Emberlight and Moorcroft Manor where you can separate by some menu that pops up? And moreover, can the lift at the left take you to not just a random floor within a depth but a random depth within the next stratum as well?
-or-
Can the regular lift/elevator/gate (I cannot remember now for as sleepy as I am) at the right be made to act as the ones do at Depth 8 and 18?
If people want to go up they can just press ESC > Return To Haven, or stand on the elevator on the right and click "Quit Expedition". There's no need for the elevator on the left anymore.
