Never needed the ability to jump in FFXI (excluding Drgs in battle), so do not need it in FFXIV. Would kill the feel of exploration and make guildleve unnecessary short in the time they take to complete. FFXIII for me worked simply because it added something different to the scenery and to the fact you were going in the same direction most of the time (so more reason to hit a button to interact with the scenery).

Although saying that when you could swim short distances in FFX I was briefly disappointed there was no option to swim in FFXI. It'll pass.
