Are we forgetting a major system component here? The Stamina system? Make Jumping take a chunk of that away. simple. bunny-hopping solved. people certainly wont jump around while fighting with their stamina dropping heavily. make it take enough that at best you could perhaps do at most, 2 jumps after each other.
People say there's not enough world to be explorable by jumping. are we forgetting you can build on existing maps? why is was just this last update the dev team removed rocks from the world to make it easier to move.

Jumping has every right and possibility to be useful and increase immersion.
I also disagree with an ff13 jump feature. want to get to a camp with ledges in the way, set Auto-run and walk away and let your char deal with all the obstacles on their own while you go grab some snacks? no.
