While I disagree with your post as a whole, I'll answer this bit in particular. People have lives and not everyone can make all raid days (emergencies, real life etc.), sometimes statics are incomplete. What happens in these cases is that they go into PF and PUG someone. A lot of the time people are respectful, but we have entire raid nights ruined because of PUGs lying, not pulling the DPS, not understanding the mechanics, and that just isn't justifiable when we requested someone who is on the same level as our group.
This isn't even taking into account people that don't have statics and rely on PF to farm for their gear. Here is a question: If I advertised a Thordan bird farming group, why shouldn't I fully expect everyone to be competent at this mechanic intensive fight? And why shouldn't I want measures to make sure that the entire session won't turn into someone joining for the clear and then leaving when they have it (best case scenario, worst case is they completely screw us and we have to disband)
