A lot of people at the end of the day just want to sample "The End Game" and some feel nervous having another 5 people depend on them, so maybe they have ran the Vault a handful of times, I would say once you have ran it at least 10 times you get the hang of it it’s not exactly complicated stuff. But they obviously have some of the basics and probably took 20mins to find your group and fear being booted and just want another carry. Avoiding the relic etc though will never make you any better at it – that’s why for a few runs force (used loosely) a new person to have a go with it and no pressure, once they done it one run they’ll forever know how to run the relic it as like I say its not actually complicated, makes me laugh when people say they are brilliant with the relic…..the equivalent of saying you great at walking......*rolls eyes*
