That's just falling to your death, I'm talking about a big chunk of your shields gone or blinking after an enemy has boarded your Banshee and booted your ass off the highest point of Coagulation. 

Not just the Banshee. You can jump from rediculous heights and not feel a thing in HALO 2. At the very least, they should have it so that if you wear an opponents shields down, and they are forced to jump off the hight point of a map, they die.Fall damage would be horrible since you only have a shield...only way I'd like to see it used is when falling from a Banshee.
