I haven't read the entire thread, so forgive me if this was mentioned already but... Didn't a dev post say that jump would be used to interrupt casts as well? That would imply we could freely jump whenever we wanted, and not like how FFXIII was.

Personally, I don't care either way as long as the animation is smooth and looks nice. I think being worried about people making bots that jump 24/7 is a little silly.
