Below Need, above Greed. Companion Need.
I am all for this, but I would add forced criteria to being able to click need in the first place as in if you cant equip the item on your character you can't even press the need button.
The fact is unless its forced while in a pug you never can tell, why even give the ninja the option to need if they don't like your chosen loot options they can get another group.
So I would ask for your system need/companion need/greed but forced specifically for when you don't know your group members.
