Its simple.
The entire world has changed in shape and size, causing less gravity.
less gravity = huge jumps - damage

Because of some rough terrain, I'm glad there is no fall damage.
EGO implant takes care about gravitation and fall damage.
I would certainly think if not taking damage or dying that you are stunned as your Ego-increased body recovers from the shock-trauma.
Not stunned, but "staggered". You know, snared by 75% for a time.
But I would rather have people just take damage. I wouldn't mind meleeing someone off a cliff or having a blast propel them off one and then watching them fall to their death.
