Let me put it into perspective for you with two scenarios.
First Scenario (current community standard)
A piece of loot drops and it is an Elemental Flake. Every single person in the group wants this so they all roll GREED except, one person decides to wait and roll need at the last minute, therefore overtaking the greed rolls and receives the loot. This is a flawed system because it gives room for error and people can take the loot last minute if they don't follow the community standard.
Second Scenario (the way I think it should be)
A piece of loot drops and it is an Elemental Flake. Every single person in the group wants this so they all roll NEED. The system rolls and someone receives the loot fairly based on the rolls. There is no room for error and no way that someone can take the loot last minute.
Look,everyone need everything. But yes true, you have a point there "why do all people greed instead of need?"
Simple, there is a lot of problem if people choose need every single time/most of the time instead of greed it.
Once you run a couple of dungeon, there will be a lot of drops from mobs, and it would be very problematic to choose every single time what to greed and what to need. It is much simpler to greed everytime or need everytime....
Then why not need instead of greed?
This is not big problem if all stuff is not bound, at least until we equip them.
In higher lvl, for example, in lvl 45 dungeon, there is some very rare specific-class-equip drops that is equivalent to like 12 dungeon run (non supporter) and they cant be traded, they bind on pickup. If everyone mindlessly choose need in most of time, a person or two might misclick "need" and that would screw the one who ACTUALLY needs it.
So people here usually reserve the "need" for only that occassion. For the class specific eq, in which they are bind-on-pickup.
