Please no combat use.

Please yes zone / exploration use, as long as you somehow set it up such that people can /follow you and if you jump, they jump as well to keep up with you.

Double please yes places you can only jump to with a buff active or while on a chocobo after it's been fed gysahl greens or whatever as shortcuts through zones, or scenic routes, although it's probably too late for that kind of idea to make it into zone design.

Also Lalafell should be immune to falling damage by virtue of natural resistance due to being punted constantly.
