Jumping? Screw jumping. I want to friggin' CLIMB those stupid little hills you can't see on the map. Is that really so much to ask for?

Personally, the thought of a 'Jump' button in this game terrifies me. Final Fantasy XIV aims to have a bit of a realism factor, so just jumping around 20 feet like a jackass whenever you want is a bit out of the question. Of course.
But I agree with you.. They should just make little ledges and things like that climbable. It would add a whole lot more depth to the game and make it feel twenty times greater of the experience, the main reason why I bought the game in the first place.

This is obviously a hugely wanted factor of the game by the fans, and I truly hope that Square-Enix listens and eventually delivers, unlike they did with Final Fantasy XI.
And what if you want to cross the map quickly? You should be able to just take a leap off of a high ledge rather than going around it. Sure, if the hill is like two stories tall, I can understand that being dangerous to jump off of. So make that unavailable, SE. As you did with FFX-2-- Only make it so you can jump from certain variable marked areas. I haven't played anything that's FFXII and beyond, so I can't say much about the newer features they've shown in newer games. But if they even turned their head to the word 'Jumping' in any game, they should really consider this. I've been wanting a Jumping and Climbing feature in FFXI for the last five years, for crying out loud.
