so like you have team chests and a personal chest. in a personal chest you can put anything in there, but in the team chest you can put stuff and ur team can steal it.
The thing I can see to counter this is that it would take emeralds and whatever other materials out of the games circulation. Your team gets eliminated? Those emeralds might as well be in the void. It lessens rewards for when killing a player. Maybe if the person that kills you gets stuff from your personal chest might balance it out but I just see it as unnecessary.
