Every other fight has a big red button - that is, something that your fireteam does to start the fight. Crota, you stand as a full fireteam on the crystal. Oryx, you approach the echo. Aksis, you shoot him in the face. Atheon... just kinda does his own thing. It means you have little to no time after a wipe to talk about what happened and adjust your strategy. Please add some sort of buffer to prevent the encounter from starting immediately after the end of Gatekeeper or after a wipe.
