I like push.... jump seems most of the time like an exploit... oh? I am in a fire surface, better jump out instead of run, ooh there is a tank between me and their wizard? I can jump out and avoid the tank ezplz. I will tone down hard the jump ability to all classes.
Kinda of, but having to use my bonus action to jump away uses it up, so I can't use a healing item or dip my weapon in fire/poison or cast a bonus action spell.
Oh or stab with my second hand weapon(for an extra attack).
