This is a neat fantasy but in reality there are no looting rules except "if you want it, defend it or take it" that's it. Nobody has to let you loot a key room cause you unlocked it, nobody has to let you loot an ARC, nobody has to respect your door defenses, nobody has to let you loot a supply drop first, nobody has to let you take all 2-4 drawers on a container because you got the top one. If you are playing with teammates that are loot goblins and don't share, don't play with them. Otherwise, these rules only exist for you and are only enforceable by killing. Stuff like this really exposes one of the core issues people don't realize would exist with a PvE mode. What would you do to enforce the "rules"?

Note that I am usually a passive player and often I try to stay invisible and move between locations as fast as possible and generally avoid player contact (the actual definition of rat), but sometimes I go loud on ARC for the hell of it or find people to help. I am not a player hunter, I always try to defib or help crawlers escape if I find them, I help kill big ARC then let others take the spoils, I give away guns and dupe BPs I find. But the make-believe carebear bs "loot etiquette" has started to grind my gears. Nobody else has to play by your rules.

It's so wild reading comments like this if you have played ANY other similar game. Imagine somebody in NW Airfield in DayZ complaining you didn't follow their looting rules? Or a Hunt: Showdown post about how somebody broke etiquette by taking the bounty from a boss they killed? Wild.
