Its too easy to hide a body for no one to find and loot.
Lets say you are on the north east airfield, you just looted it all, and now you are in a firefight with a player. You kill him. Now you have a problem because maybe you dont have room for his gear and weapons and maybe you dont have time.
"hide body"
problem solved.
Its to easy, it should require a tool and animation to hide a body, not just the click of a button.
This is my opinion, but its seems right.
[Maybe is shouldnt necessarily require a tool, but atleast time and animation).
