Dislodged Foreign Object is the reason why I believe we should ALWAYS use Master Loot.
Reason: Dislodged Foreign Object dropped after around 10 kills of Rotface, I had killed him 10 times and it had never dropped, somebody else had just joined the Guild on the day when it finally dropped. We always run Master Looter, but on this day our Raid Leaders forgot, and this person out-rolled me. Yes, some may say Need Before Greed is fairer and he won fair and square, and I agree. But I had worked hard for that drop, and that person had not. (He even died in the attempted and argued at the healers). Definately not deserving of the loot he got.
Although everything happens for a reason, because the next week, we downed Rotface on Heroic, and Dislodged Foreign Object has dropped, if I had won it the week before, then I would have been stuck with the normal version.
