Tagging system in PvE maps

The game need some sort of tagging system to avoid loot being stolen in PvE maps. Currently there’s no point in trying to farm larger enemies since anybody can just zoom in at the last second and loot everything before you have the chance to get near the body. Just make it so loot gets locked to whoever dealt the first point of damage for a set amount of time (like 1 minute or so). That way ownership is guaranteed and random people that come after get to have the scraps. Only for PvE maps tho.
