Knockback and fall damage (Discussion)
It would be a good idea if there was a new mechanic where you could knock people backwards it would be handy if you were fighting on a cliff or something and knocked them off it and damaged them from the fall.


 * Why this is a good idea
 * It would add a new angle to combat
 * It uses the z-axis making combat more interesting
 * It'll make the game MUCH more realistic, good realistic. Can create a new fighting style, like the speed kill in Prince of Persia...
 * That would be fun knocking someone off of a cliff....300 pit of death style


 * Why it may not work out
 * It may be hard to implement
 * No way to res if you get knocked off a 1000 foot cliff.
