The point is that there are so many other issues that need to be resolved before even considering the addition of a jump feature. That's a big reason why it's such a concern at this point.
I have yet to see anyone argue in favor of adding the jump feature other than "Woot" or "Yay" and getting over small objects.
Honestly are there really small rocks and obststacles that you cannot run over or around now? If you think that jump is going to allow you to move faster or in a straight line, then you are wrong.
They definitley should allow you to turn off the animation and ban it from cities like chocobos.
It's sad to see them adding this to FF. It was more unique in not having the feature. It is not a standard that adds to gameplay.
