I've had this problem with pickup groups before, where I was the only one experienced/willing to handle the relic. By the time we got to the Gatekeeper I had to teach one of the guys but we got through it. Atheon was tough, we wiped several times but finally got it when me and the other guy had runs where we were teleported each time. A lot of the high level people with relic experience have probably either stopped playing or don't run the vault anymore.
