General Aetheon tips I'd add: 1). on mars (left) always allow the relic holder to get the first hit on the adds in the timestreams, shooting before this alerts adds to your presence and he will get sniped, on the right side he should go for the goblins before the praetorian, and you can shoot the praetorian when hes on top of the goblins. 2) . Killing the oracles as soon as they start to spawn after the aetheon teleport means you can kill them quickly, without a full clip of epilogue for example (hard raid), if you wait too long it takes more ammo. This can allow one person to kill the first few oracles alone. and facilitate someone helping on the adds, so if someone gets the oracles straight off the bat everything should be peachy. 3). If you are opening the portal and the other guys have the supplicants covered you can go into/through the portal you just opened and help kill oracles if group inside is struggling. (communicate before doing this) 4). focus on the supplicants on the portal that has your team in, only pick off the other side when waiting for respawns if at all. (assumes shield guy bubbles on the middle island) 5). a flash grenade or with the exotic helm blind effect on titan bubble can be very helpful for killing the praetorian when warped to venus/right 6). use weapons of light in boss fight if available 7). every one shoot the boss, do not think "i should really clear these supplicants first". The more damage on boss the less teleports, leave the supplicants for the group outside to mop up 8) relic holder let people know 5 seconds until the shield drops, and make sure they know that means get out of here. 9). relic holder in vengence time ensure the relics over shield is towards the front of the middle island, and away from the pillar on the left of that middle island to avoid deaths from splash damage. 10). you shouldn't have to ask which side/portal needs to be opened, its on the minimap. (arrow pointing off the minimap on the left or right) guys inside tell them anyway (once roles inside are sorted)
