I think tying shatter dive to a hunters jump height might make more sense. The specifics I am thinking of is that the closer you are to your max jump height the more effective the shatter dive is Therefor requiring you to more or less be at the apex of your jump making you more vulnerable and more obvious that your about to dunked on by a shatter dive. Or: you need to be at least this high off the ground to activate shatter dive either one fulfills the change I am thinking of
