I know you guys are swamped, and this is an alpha. But serious thought needs to be put into how the characters interact with their environment. As a "survivalist" in this game, I shouldnt hurt myself going off of a small ledge. At the least if I am crouched when I "fall off" of it, I should be able to take minimal damage. I know this is a simulator, and not an action game per se, but the physics in the ArmA engine are god awful when it comes to this stuff.
