Re: How often do you encounter these types of randoms?
@decimation92 It could just maybe also have to do with the fact that there is literally an in-game hint on the loading screen telling you that it is bad sportsmanship to take the items your team mates have "Dibsed."
You are free to go ahead and take their stuff, but you don't get to claim that the game didn't intend the dibs mechanism. It should be obvious why you are able to take things even if someone else dibsed it. Your team mates could troll you and dibs every item that is pinged.
Are there cases where team mates abuse the dibs system to a point where you will ignore their dibs? Yes. But if you don't respect the system as a rule, then don't expect any boxes to hit the ground when you say "I need light ammo."
