I hope they put this to a poll. I see a lot of people speaking as if they are the voice of the community, but I for one would like a jump--and considering this game is, unlike FFXIII, very open and quite non-linear, the FFXIII jump function would not work as well.
Being able to jump and keeping atmosphere are not mutually exclusive. For instance, Miqo'te and Lalafell both seem as though they would jump quite a bit. Besides this, as mentioned above there are often instances where being able to jump would save a lot of frustration regarding mobs on different levels of terrain, or just getting around. A lot of the commentary now and on the fansites seems to be close to "I don't want it, so no one else should have it". I would like the choice.
