Heh, I was in a hardcore raid guild in the 60 days. I raided as a healing priest and had perfect attendance from the first pull in ZG to the first kill of Ragnaros. I was first in line for benediction and had more DKP than anyone else in the guild due to my attendance + being nice and passing gear to the poorly played priests because I knew I could still out-heal them all in blues while their in T1. So finally our first drop off major domo for benediction comes. I had already completed all the quests and had the other pieces to make benediction on the spot. When I announced this as they asked the priests who should get the first one, our guild leader told me I was a traitor to the guild and an ass for not telling the other priests that they can pre-complete the quest chain and get the other item (like it wasn't common knowledge and I thought everyone knew, we had been farming the eyes for weeks). So he stripped me of all DKP and my lead priest spot and gave the item to his best friend who happened to have an alt priest we we're gearing with MC on farm status.

This guild had a simple name that confused everyone and was misspelled the same way constantly. I logged after the raid and created a lvl1 bank toon with the same spelling as the commonly misspelled bank toon and that guild single handedly funded my first multi-box group.
