Well, that didn't take long...
During the SFK Arugal encounter on my first PuG run since my re-roll, I fell victim to the classic loot ninja. Just before Arugal fell, I noticed that the looting method had been changed to Master Looter. The guy was after Arugal's Robes, and since there were 3 other casters in the group, he and his accomplice (who invited the ninja into the group just before we entered Arugal's chamber) didn't want to chance it. Thankfully, karma conspired against him and Arugal dropped his Belt instead.
Anyhow, it's not surprising that there's a selfish douchebag out there that resorts to childish means to get what he wants. What is sickeningly shocking, however, is how the Game Masters respond to such "dishonorable" behaviors.
Later today, I'll write about what two GMs had to say, and why Blizzard is terribly wrong in their lack of policing b.s. For now, sleep. I was ganked way too many times tonight -- makes me tired. =)
