I can't help but wonder if creating alternates to run the raid reduces your chances at getting gear. I only have one raid-worthy character and I got all the gear I need (helm, gauntlets x2, boots), plus the Mythoclast (and three Chatterwhites, a Sparrow, AE, VoC, the ship, and PR) from four lootable raids. My raid 'mentor' runs three characters for six raids a week, and doesn't have all the raid gear he needs. Makes me wonder.
