Alpha Loot personally i like alpha with a certain monetary value set before moving on Yes, alpha looting directed by the group leader. This way if a person is not following the order the leader can boot them to make a point. In that everyone has a chance to loot the item. Once you've looted an item, you are out of all special loots until all else have one. In my guild format though often the loot will go to who needs it and will use it.
