If you are in a raid and you would like another member of the team to get a drop then don’t tell the raid leader you’re interested in the item.
Our Holy Pally relayed to me a chat he had with our priest after the priest got The Impossible Dream from 25-man Loatheb.
By the way our Pally has run Heroic Nexus nine times now trying to get The War Mace of Unrequited Love to drop. Maybe the tenth time will be the charm.
