For myself, I don't think anything quite approaches the sheer agony of having accidentally passed on Idol of Worship from Grand Widow Faerlina just because I wasn't paying attention at the time. I don't do much cat DPS, but losing the best-in-slot idol directly affecting the attack (Rip) that contributes the largest share of feral DPS is...again with the ouch. I still ask myself what was so amazingly enthralling about tanking Maexxna trash that night that I could have zoned out to that degree, and -- naturally! -- the idol never dropped again. While I guess it's possible that there are players out there who are practically perfect in every way and have never missed a drop, I have the sneaking suspicion that most of us still find a reason to kick ourselves.
