Ok, that's the official behavior, but Depth is not an instance, I'm not going to skip a part of a mission or skip something because I can use Leap. My suggestion is to alter the official behavior of the skill on only that map to make the game more fair and balanced with the SE/SA classes, that is, to use the same criteria: allow all displacement skills (Body Recolation, Back Slide, Fallen Angel, Lope and Leap) or do not allow any.
From my point of view, it seems fair to allow them all, since the only one that I think is disabled is Leap.
