Last time one of our clan (a raid virgin then) was trying to get that secret chest before the Warpriest encounter. Most of us were by the second set of plates waiting for him (he had struggled on the tombships part too; I had stayed behind to call out his jumps for him) and although we couldn't really see him through the doorway we kept cracking up watching his gamertag drift up, up upppp... Then plummet straight down. He got pretty pissed but finally got it on his 8th or 9th try.
