If you don't like jump just don't use it amirite.

Joking aside. No idea what the problem is, it's a 2 second action. It removes invisible walls (or at least it should). If people enjoy their restricted world, then sure, no jumping. Xenoblade felt much more vibrant than FFXII did because you could explore with a jump function. Nothing was truly held behind an invisible wall. Right now you gotta walk around every rock, can't drop down from cliffs, etc. It's a little silly that we can't do simple things like this to get to various places. Not really saying I think that those against jumping are wrong, I just cannot see what they have against a simple feature like that. Even FFXIII-2 has manual jumping.
