I also notice a huge trend of, people who have "beaten" the raid. But haven't done anything besides Oryx. Sadly I'm not lucky enough to be part of a dedicated raid team so I have to rely on LFG for invites, and that's only when people have the decency to respond. I've only gotten as far as the Sisters before everyone leaves, and it takes forever to find new people, because everyone is bad and impatient.
