pvp drop crit idea

I have an idea for the Jump crit we already Have What if we got a drop crit like the higher you fall from the more damage you will do to the person or mob with the obvious trade off of the fall damage it would even make jump boost potions more useful in pvp slightly boosting your crit damage with an axe or sword if you timed it right I guess its just a revamp to the current jump crit system
