I thought we'd lost him after he fell from the platforms on the last Oryx circuit then went really quiet.
We did use a lot of time fannying about looking for chests and calcified fragments and considering a few of us hadn't seen all of the sections of the raid before it was a decent run. We could knock a huge chunk of time off that and I reckon it won't be long until we're just blasting through it wondering what all the fuss was about.
Plus after we finished I collected my 50 hadium flakes and am on to the last part of the Eris quest for the exotic scout. I hear that thing absolutely wrecks the witches and Oryx, more so than even black spindle.
