I'll go all out for jumping if they add two things...

The ability to jump up a mountain preferably a volcano of sorts...cough the one above Limsa...cough...or up a great mana tree cough and cough.

Secondly, PLATFORMING/PUZZLES...add obnoxious platforming to dungeons...YES it'll be obnoxious...OMG I fell into the crevasse...ooh I'm dead there were spikes down there. Really bloody death...BUT I WANT THIS SO BADLY no matter how obnoxious it'll be.
