There's no need for a master loot system here. If someone can need on an item, expect them to... Thier time is as valuable as yours.

In fact, master loot is only going to cause a larger problem. That impatient person in Party Finder (The one going GARUDA EX, EXP ONLY, 1 DEATH UR KICKED!!!) is going to master loot because he already has zero patience and doesnt want to run it more than he has to (thus the exp only) Therefor, cheating people out of a chance of the item they earned.
