To me we really need to see, or discuss not just yes/no jumping. But if theres jumping what kind of jumping are we discussing?

Bunny hops?
A real jump where you have to really leap with your legs and knees.
Or are we lunging with full power with the need to steady ourselves at the landing?

Jumping for the sake of jumping, i don't subscribe to myself. I think a game can be just fine without it. But if its not animated like a jump that impacts your movement like a jump, and gives you not a requirement, but a reason to jump then its fine.

If its hopping just to hop, oh and go over fences, then it hardly matters no matter what people use it for, be it Boredom, annoyance or whatever.
