Most people want to get the raid done as quickly as possible so that they can get their loot. Most of the time, people are just after the exotics. They don't want to have to spend any time teaching or carrying inexperienced players when they can just fill up their group with high levels and get it done faster. But at this point, 32 doesn't mean you have even touched VoG. I've seen plenty of high level players who have no idea what to do. And I guide them through it the exact same way I would guide through a sub-30 player. Level doesn't automatically mean you know what you're doing, but it does make it easy to tell who will be doing more damage (up to the level of the raid, that is).
