The real kicker is being 1 ilevel lower than the requirement and you have beaten that boss before, are a very good raider, have excellent raid awareness and still can't get the group that can roll the boss over.
That and the last time I joined a pug group that did one shot the boss the raid leader kicked everyone and ninja'd the loot, which according to Blizzard he can do because he never promised to dispense loot in any way and he can dispense it any way he or she chooses.
