As I'm sure the devs are bound to have noticed by now, there are plenty of groups forming in party finder that advertise as greed parties for primal content. I've made a few of these parties myself and find it distressing that there's no way for the party leader to set the loot rules to greed only, so that everyone has a chance at the items.

I understand that if implemented, this may cause a lot of parties to set it to greed only as default. So here's an idea that may work: Perhaps it can be something like a vote system, where the leader initiates the change, and everyone in the party must vote yes to disable the need option for it to go through. In the event that even one person votes no, the loot system remains as is with the need option available this would help avoid situations where say, a party made up mostly of friends tries to change the loot system to gain a loot advantage for a friend over a pick up member.

Perhaps others may have more ideas as to how this may work, but I feel we definitely need an option to at least disable the Need option to avoid ninja looting given the popularity of greed only parties.
