I love trying to push them of the map, but they weigh so much in game they're VERY hard to move. I've only knocked a chest of the map twice both on Titan from the enemy supplies. The time it takes to move the chest it's no threat to anyone as most of the time you'll just barely have enough time to push it off. With confidence I can say I've never stopped anyone from obtaining loot; however I've seen people reviving other players who died on an edge only for them to immediately fall and die over and over again preventing them from getting loot. <That is a much bigger issue. (I try to push everything off the map public event bosses, high priority targets, friends, vehicles, random enemies, and those darn boxes) I'd [b]LOVE[/b] to push a fallen walker into the ocean on Titan.
