I understand that ppl make mistakes BrianStephan, but mistakes costs lives
Tell the two id10ts in your ex guild to go do their homework or something, the problem has been rectified and the guy that came second got his loot, end of discussion.
While we on this roll philosophy. I check what loot dropped as soon as it's clear to do so (you never know if some dumb rogue forgot to step out of the fire and released after he died....that after he "/yell DAMN N00B HEALERS!!!!"[jk]). Once I went through all the loot and scanned what I can use, I start comparing and I always make sure that it is an upgrade before I type /roll and wait for the announcement to roll for item ABC.
With 3.1 and duel spec looming, I will ALWAYS ask all other similar classes/specs of my intention to gear up a certain kit and ask permission to roll on loot if it should drop, I then make it known to the raid leader/loot master of the responses I got. I got the T7 Elemental gloves in VoA hc the other day (I'm still enhancement) and the one guy imediately shouted but I am Enhance....BUT, because I asked everybody (including this guy) and made it known to the raid leader/loot master, the discussion ended even before it began.
