Unfortuneately, Yoshi may remove jump because of the complaining. Because generally when something is implemented or is going to be implemented, the only real feedback they hear are the complainers. The most vocal are the one's who dislike something, the one's who like it are generally playing the game.

Jump should be implemented, the reason is in the OP. Where he mentions ifrit. When he throws down the void, you can slowly run out of it or you could instantly jump out of it. 1 or 2 secs of void damage, or no void damage. Hmmm, its not rocket science incase your wondering which i'd prefer.
