Why can't them mob drop multiples of the same item based on the number of parties/people fighting it and just make the loot drops only lottable by each separate group and reduce the number of items a nm drops per group based on the number of people in each group. Personally i'd rather see everyone with potential for rewards for thier groups seperately then repeat sitting in Dragon's Aery every day for 3 hours fighting for claims. There just has to be be a better way.
