I think it would be cool if you could slide a farther distance depending on the steepness of the terrain that you are on and what material it is. I don't know how hard this would be to implement, but if it is not to time consuming it would be a great addition to the game.
@zulu Do you mean because it gets you killed (personally, i have a habit from of crouching when fighting in close quarters, or if the enemy catches me by suprise. You see how this may become a problem if im running before that happens)? or because its to hard reach or?
