Let leader assign who gets drop in a G>N party. Groups fall apart because of one person either needing or greeding other peoples items.

Let it be something you can only change outside of instance and something the party agrees with.

So simple once leader Q's the item you want pops up in the Q and if you accept that means you agree.

Bring this in ASAP, some items are rarely seen and when they drop its not fair that someone else takes it.
