As is this. It is up to players to manage loot rules within their own groups. Any group that fails to set rules, fails to set rules. There is no fallback default assumed rules, and GMs will not assist with disputes.
As to your point on “waste of time to create” It is. They should have reverted to the original phrasing on need restrictions from beta: “Same item, same ilvl” Not the “same item, same or higher ilvl” that we currently have.
