While I think you make some valid points I think you should expand point #4 to include Leadership Competency. While it doesn't sound like you personally have this problem (you seem very organized actually) in my experience in the raid so far this has been the major turn off for me in PUG groups. The leader should lead, that's what he does, while under-qualified, under-performing players should take heed to not make themselves a burden, its the leader's job to trim the fat so to speak. The leader should get verbal responses from everyone to make sure the mic is working, the leader should either have people list their gear, or inspect every player, the leader should "assign roles" as much as he can (ie some players like relic, some players like DPS) The leader should have more than just a working knowledge of the raid (I would go so far as to say the leader should know the raid better then anyone else on the team) and I know it might be harsh but if someone isn't in line in the party I think the leader should kick and replace as needed. I've been in far too many raid groups that end in disaster because the leader just didn't lead.
