DRG: Why no reduced fall damage?

[Zankes]

You're all aware you can Elusive Jump off ledges and take no fall damage, right?

For some reason in the latest dungeons such as Qarn HM and Hullbreaker, there is invisible wall preventing us Dragoons using Elusive Jump in such a manner that we could avoid taking fall damage. It stops us from going down and after wasting the Elusive Jump we are still top of the ledge and we are forced to go down by taking damage. Last dungeon where I recall that I could use Elusive Jump without any issues was Copperbell HM.
