Well the Gatekeeper and Atheon stages are completely separate the process is this: 1) Go in each portal, pick up the Relics, one person defends centre Conflux 2) When both Relics are outside, defend the central Conflux, Relics disappear 3) Get rewards, Atheon comes out 4) Wait a bit and do the Atheon Oracle/T'sV part Now, two things strike me as odd at point 2 above: 1) Having 6 guardians is massively overkill - Why aren't there more enemies to keep all 6 guardians occupied? - There's only 3 points at which Minotaurs come down from and each point on its own is no more difficult than when one person guards the Conflux at point 1 above 2) The entrance door is open again at the stage and shuts in about 5 seconds after the Relics disappear - Why have they programmed that in? - Yet people have tried going out and looking around but nothing can be found. Edit: The main concern I have with your theory is that it relies solely on the Warlock and the self-res. If there was something tied to this then I'd be very surprised as it could essentially limit people getting loot based on the members of their fireteam
