WOW. What an amazing idea. This is why I love these forums. This would be a great addition to the Halo franchise for many different reasons. Firstly, it is a realistic way to add a feature that makes people stop complaining about fall damage. Its simple physics, this is why they talk about knowing how to fall in sports sometimes. How you do it has a large effect on the damage that you sustain.
Secondly, this would add a skill feature to the game. As long as it's not too easy to do this could be a fun and competetive feature in War Games.
Liked for sure.
